Failed attempt to resolve the warnings via implicit priorities

[MateuszKubuszok]

This PR was created only to document that using implicit priorities to solve the new 3.7-givens behavior have failed: Scala 3.5.1 still generates the warnings that would become failures in 3.7.

I gave up on fixing this issue in backward compatible way, the only way I found - https://scastie.scala-lang.org/eKrwKqN8S2uHp5pjr61uiw - is a breaking change that might not be cross-compilable.
