They'd have to outlaw compilers to make that work.
Say (hypothetically) they forced KDE and Gnome to do that - they are open source, you can't hide that it was done, someone will rip out that part and either compile and release a new distro or post the git somewhere outside that jurisdiction and someone else will do it.
This isn't a new thing even - we've had free/non-free/rpmfusion and the like for decades - hell back in the day I had to pull and compile freetype because of the patent on subpixel hinting that was valid in the US and not in the EU.
The one that does worry me more is that they straight up just start locking down the hardware more strictly - a mobile phone style attestation/locked bootloaders would be a major challenge to open computing.
