Rules in sports are always being adjusted, and participants are always looking for (barely legal) ways to get around them.

Example: In cycling, they banned narrow handlebars. There's an aero advantage, but it was seen as a safety problem. So cyclists canted their brake hoods way inside, rested their hands on the brake hoods, and got an aero advantage.

And now there's a rule about brake hoods. Laws are meant only be living things that change as society changes, and also change to patch what we might call "exploits." You are perfectly correct: It's never one and done, it's an ongoing process.

This is part of why a lot of EU directives are almost 50% "why this law is necessary and what we're trying to achieve", 30% "what needs to be implemented", and then 20% "who's going to look after all of this and how".

That way, a misplaced comma or a wonky sentence doesn't allow for easy loopholes that need tighter laws to fix issues.

Now law text will work forever, but this format makes for a very solid foundation.
