Well, usually there should be no API-breaking changes between Emacs X.Y
und X.Z, so version-checks more detailed than major version shouldn't be
needed.

And there is already

  (version<= "28.0" emacs-version)

if you want to test with version strings and have more control over
minor and even micro version.  (Using floats for versions is just plain
wrong.)
