Editions make the problem worse by requiring the version not only to support the underlying pragmas but also to understand the edition mapping.
Example: PRAGMA foo=1 is introduced in 2027. PRAGMA edition=2030 implies this foo pragma. Now you unnecessarily lock out three years worth of releases.
I don't see how you don't have the pragma compatibility problem either way. The edition proposal captures a bunch of behaviors that already exist.
Yes, the problem exists either way. Editions just exacerbate the problem.
