So nothing prevents one using gendec.eu to generate a UK GAR form for a flight Shoreham to Alderney?
I think we’ve done this before but gendec.eu is a dead URL. They have their server poorly set up. You have to use at least www.gendec.eu, and probably the fashionable civil-liberties-safeguarding form 
is https://www.gendec.eu/
How do they plan to make money?

They are listed on https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1043233/GOV.UK_GAR_instructions_-_December_2021.pdf on page 16 under “Annex G 3rd Party Applications with secure links to Home Office systems”. So no, that is not (paraphrasing you) “some form” that some not very happy person enters into their system manually, but the data is submitted directly electronically (just like OnlineGAR does).
ICAO “health” GENDEC exists in UK, it’s called C155, it’s mostly about sars, zika, smallpox…
Immigration PN, pre-avis, GAR…are completely different from GENDEC

Quite right about Declaration of Health just revisited Annexe 9 appendix1.
I’m not sure how it deals with immigration because it doesn’t ask for passport nos or any of the normal immigration questions.

The GenDec originated from Declaration of Health to help fight spreading diseases by aviation PAX and was launched together with (im)migration application.
The Gendec has been included in ICAO AIUI since the Chicago Convention was drawn up in 1944 effective 1947. I was under the impression that the UK GAR was something totally different.

I could believe that it generates “some form” which goes to the UK BF where some not very happy person enters it into their system manually. The UK GAR is either a .xlsx file (which is processed with some script into a database) or the data is submitted directly electronically (which OnlineGAR does, and airlines have been doing since for ever). I do know UK BF still accept GARs in old formats and enter them by hand, because they told me so 
Looks like much of Europe has jumped on the Gendec/GAR bandwagon and is doing it mostly very badly.
which they oddly called GAR
The UK GAR is > 20 years old, predating anything I know about (actually used) in Europe except the Greek “gendec” declaring you don’t have tuberculosis It is also a great idea since just about every UK runway has Immigration/Customs; something which none of the “Gendecs” do. They are just data collection projects.
I have used the site a couple of times and it works on the Dutch side of the border fine and on the UK side too I think. Athough I’ve only been checked in NL and never in the UK, I did e-mail with the borderforce regarding changes in my flight plan and the alway seemed informed about the stuff I filed through the GenDec site.
The GenDec discusson is a rather old one, I guess.
When I was doing the ‘how to do cross border flights’ extension of our training facility after passing PPL, we were taught each and every flight has to be able to present a General Declaration GenDec according to ICAO Annex 9, Appendix 1. We learned to keep blank copies of APP-1 at any time in the aircraft in case anybody ever asks for it, as ICAO does not require in general preparing one in advance of the flight but only on request. The UK was one of the few countries requiring a ‘GenDec’, which they oddly called GAR. The Netherlands and some other countries jumped on the Bandwaggon, maybe there are so many bored from pandemic and looking for new ways to <…> pilots.
I do welcome effort like OnlineGAR and Gendec.eu, but benefits are limited, indeed.
A great idea which eases UK to NL flights. Thanks to those who did it.
Hopefully, it will work with more countries.
OnlineGAR says it works with Dutch customs BTW.
