I agree that this is a possible negative.

Modernizing idlelib names, in relation to PEP 434, is a separate discussion.

The Format menu now has 'Strip trailing whitespace', which may be new 
since you last looked.  It needs to strip trailing blank lines, as 
reindent.py does, in addition to trailing whitespace on each line, to 
make files ready to commit to the cpython repository.  Did you have in 
mind also doing within-line cleanups (as a separate menu entry)?
