I most certainly welcome laws like this, partly because I work in a place, where compliance always wins, and a11y being part of compliance makes it more of real requirement and less of "nice to have".

That being said, I saw two approaches to this -- negative, when people get some kind of a tool and change things until the tool stops showing warning and positive, where accessibility is another part of UX and has to be designed with positive checks on what actually works.

I sincerely hope that the team behind it is doing it the second way, but I'm not in their heads and don't know whether this text war written as part of government relations to get the moneys or they actually believe it. It's customary to praise Communist party, God allmighty without meaning any of it in some places too.
