Here's the simplification proposed by IAOPA(Europe):
"IAOPA (Europe) requests support for a simplification of Annex 1 and Article 2(8) flight time recognition as follows:
Flight time on Annex 1(a)-(d) aircraft may be recognised without limitation.
Flight time on Annex 1(e) & (g) aircraft may be recognised for rating revalidation or LAPL privilege extension purposes only.
Flight time on aircraft defined in Article 2 (8) of Regulation (EU) 2018/1139 may be recognised for rating revalidation or LAPL privilege extension purposes only."
The use of Annex 1 (a)-(d) for training is regulated elsewhere in the Aircrew Regulation - we are only talking about flight time in such aircraft.
In the UK, now that we are no longer part of EASA, we are able to take a more pragmatic and simple stance towards flight time in 'non Part 21' aircraft.
