The EU regulation we’re talking about essentially does, with an exception for high cycle batteries on waterproof phones
replyNo, it doesn't require a battery door, even for phones that don't meet the exception you mentioned.
replyOver a decade ago, I replaced a phone screen over a few hours, involving a couple dozen screws. During that, I had to remove the battery. (Replacing only the battery would have been easier.) I'm a layman, and all the screws were Phillips. That's sufficient to be replaceable.
