I can’t decipher the relevance of half the posts no matter how I read them. Neither can others…
I think it’s worth discussing SERA.8015 in this context, I am not sure why you think it’s irrelevant?
I see lot of flaws for this to apply,
SERA.8015: when vectoring or assigning a direct routing not included in the flight plan, which takes an IFR flight off published ATS route or instrument procedure, an air traffic controller providing ATS surveillance service shall issue clearances such that the prescribed obstacle clearance exists at all times until the aircraft reaches the point where the pilot re-joins the flight plan route or joins a published ATS route or instrument procedure
“Radar & Approach ATC owns obstacle clearance”, AFAIK this is wrong in few situations when PIC is flying IFR in Golf, it will be good to have a reference?

I know that should work in my GPS: direct IAF (activate approach & load missed) and later scroll and direct IF or any other points (as long as it’s not close to FAF), still I was always told you should not do that and rather activate legs
It is very common in the US to be cleared direct to an IF to begin an approach. ATC has limitations to do that however, they are supposed to advise the pilt at least 5 NM from the IF and the intercept angle to the intermediate leg can be no more than 90 degrees. ATC can also clear the aircraft to a step down fix outside the FAF, but the intercept angle is limited to 30 degrees. One approach where most approach clearances are to the IF is found at KPAO direct to DOCAL. A similar situation exists at KJQF RNAV 20 or ILS 20, where most approach clearances are to the IF LEEMO. In these cases, activating the leg ending at the IF would not follow the clearance, but direct-to would. Some GPS navigators won’t accept direct-to the FAF, but will accept direct o any other fix on the procedure prior to the FAF.
Also, many IAF also have a PT (Procedure Turn) or HILPT (Hold In Lieu of a Procedure Turn) located at an IAF and the PT or HILPT must be flown unless one of 4 exceptions apply 1 – vectors to final, 2 – Cleared straight In, 3 No PT is charted on the segment being flown, and 4 – Timed approaches in use.
