This is fixed by #1504 which (among many other things), did this change:

We might want to backport at least this change to 4.2 / 4.1 (CC @dsnopek )

Note: It's really weird that scons 4.8 broke all from SCons.Variables import * :/

We might want to backport at least this change to 4.2 / 4.1

It's tagged for cherry-picking! It'll get pulled in when I do the next round

[Priton-CE]

It appears like SCons/scons@9b4f2eb added a __all__ list to the SCons.Variables __init__ file which is causing the issue.

From what I am gathering from the commit message this might be an intentional change.
