As a person from the UK, I'd guess this is probably one of those things where the UK government is too cowardly to do or say anything when it actually matters, but once they're certain there's no chance of any blowback at all they issue some meaningless bill that says "we were against this sort of thing all along" so it looks like they're actually doing something even though they're not.

Or it's one of those things that'll be so vaguely worded that it could apply to just about anything and they'll just use it to harass protestors and/or asylum seekers. Or maybe both!
