> As a developer, what should I import if my program/library works with e.g. the version range [1.20 .. 1.23]?

maybe change only that part of the namespace where api changed?
 
In the exporting library? In the importing library?

also, why not publish less frequently? I mean, nothing stops anyone
from making frequent changes to  a library, but why not limit number
of versions released to public?

Could you explain this in more detail, please? I don't seem to understand what you're proposing... :-/
