I don't have an authoritative answer, but at my dayjob we try to support

developers nor build servers are on the bleeding edge, and 4.0 and 3.6 are
still fairly recent on our timescale. The SCons API usually doesn't see a
lot of breaking changes.

Personally I prefer to try-catch the import instead of explicit version

    from SCons.Warnings import SConsWarning
except ImportError:
    # SCons 4.0.X and earlier
    from SCons.Warnings import Warning as SConsWarning

This class renaming was the only incompatibility we had to deal with to
support SCons-3.X in our setup, therefore I thought it was worth it.

I did wonder if this API breakage was accidental though, or if it was
