Don't make your game be a spaghetti mess of dependencies.
Or.
When you decide on your dependencies, make sure they are compatible with the regulations. The chances of middleware developers not updating their middleware and/or licenses to comply with these regulations are practically zero: there will 100% be market need for compliant middleware and others to provide it, so the existing middleware developers will update theirs too.

That's the easiest of the bunch because Steam already has at least one opensource reimplementation of the API (probably multiple) so all you have to do is drop a DLL in your game's directory and you get Steam independence.
