Sorry, but you're blaming the wrong people! NOT the CAA, it was the RAF, more specifically 22Trg Gp, who totally failed to ensure that UAS or EFT flying could be counted towards a Part-FCL licence.
At one point I was told by someone from their squirearchy that "22Gp have no knowledge of UAS training" - and on another "We can't support allowing UAS training towards a Part-FCL licence, because the instructors don't meet EASA requirements....".
With lunatics like that running the asylum of UAS/EFT these days, there's not much likelihood of any improvement without a lot of staff work, which no-one seems to think is worth pursuing these days.
I was at a CAA/EASA/industry meeting many years ago at Gatwick and asked the question "Will current military credits continue as they are under EASA?". The EASA lady assured us all that they would and the Head of Licensing nodded sagely.
But that didn't happen - because the RAF failed to make an adequate case. When their abject failure came to light, they even wrote an Internal Briefing Note telling people not to comment on the matter on social media.... Fat chance of that!
