I think most (all?) would already comply. What laptop do you see as not having a user replacable battery? Even MacBook can be swapped out pretty easily [1].
I won't name brands, but there are lots of low cost "tablet with keyboard" laptops with glued battery. Just a couple of months ago I had to ditch one.
Anyway, if most comply, why not make it mandatory? Or are these kind of directives only aimed at picking fights with manufacturers?
Note that I am not suggesting that all laptops should have USB-C chargers, that's a separate directive. I mean user replaceable batteries available for at least 5 years, without requiring major surgery to replace.
MacBooks are not easy at all. I did it twice and it's an annoying, dangerous mess (danger of tearing the battery open). Apple won't even bother with it. If you want an "official job", they will just replace the whole top shell including the keyboard, because they can't be bothered to remove the glue. And of course it's expensive because of that.
