I don’t understand this. What singles out these states from other EU member states and in what way? E.g. why is not Germany and the Netherlands included in this list!?

Sweden has also started the conversion of ground frequencies to 8.33. There is an AIC with the schedule.
Looking at that schedule, 100% of the stations are “converting” to the same frequency, just with the corresponding 8.33 channel number. I wonder what is the actual significance of this for the pilot:
The pilot transmitting will be transmitting the same signal whether on 25kHz og 8.33. No difference.
The pilot will be receiving the same signal, whether any of the two has 8.33 equipment or not. The only difference for the pilot will be the possible risk of interference from future, adjacent 8.33 frequencies.
The ground station will be transmitting the same signal whether on 25kHz og 8.33. No difference.
The ground station will be receiving the same signal, whether the airplane uses 8.33 equipment or not. The risk of interference in the ground station receiver will be tiny as any of the (more powerful) ground stations will have to very close to give any interference.
So the ground station will never know if the pilot uses 8.33 equipment or not, and the risk of the pilot having problems from that seems remote, at least for now.
And the pilot will never know if the ground station has changed to using 8.33 equipment, or if the schedule is just a paper excercise.

I wonder what is the actual significance of this for the pilot:Actually one of the stations is getting a different frequency — but even that one will be a 8.33 channel on a 25 kHz frequency. I guess the situation will be similar in most countries outside central Europe.
The significance for the pilot is that they (s)he will now be told to “Contact Bromma Tower One One Eight decimal One Zero Fife” and should dial 118.105 on the radio.

Here in Czech Republic, which is an early adopter of the 8.33 regulation, the figure is about 90%, and a few stations like PRAGUE INFORMATION are staying on 25 kHz channels. Thus, most VFR flights in uncontrolled airspace remain unaffected for practical purposes. However, this is not the case for discreet frequencies assigned by ATC to aircraft under IFR.

Officially… yes… but dialing 118.100 on the radio will also work just fine, even on a 8.33 radio.
I wonder how long it will take before the controllers to stop pronouncing “.105” and eventually give up and just say “.1”.
a question to UK folks – when are you finally finishing the change to 8.33 ? Looks there are still some 25khz…

They won’t. That just isn’t how it works. 8.33 is here. You may not like it but just accept it.
Can you post detail, Jason?
I always hear ### l### from controllers and FISOs, for a long time now.
After being told by Oban to contact 127.275, one panicking guy replied his radio only had 127.27.
