That's completely backward: Importing ‘*’ from the module makes
refactoring significantly *more* difficult.

With explicit ‘import foo; foo.lorem()’, an automated tool can know that
when ‘lorem’ changes to a different name, this module's use of
‘foo.lorem’ should also change.

With non-explicit ‘from foo import *; lorem()’, then an automated too
has *no way* of knowing that ‘lorem’ should change when you alter that
name in the ‘foo’ module.

So no, what you say above is the opposite of correct. Instead, using
star import makes a rename *more* difficult to do correctly.
