Could be.  Dunno.

Still calls out for a better argument than a vague
opinion that such a change adding incompatibility
would be "more convenient".  That's all.

The commands have different uses.  Their behavior
has long been different in this regard.  What's a
great argument for making this change?  That's the
question.

As I said:

  It's a reasonable proposal to examine.  And it
  might be the right thing to do.

  PP eval is not non-PP eval, and "more convenient"
  isn't a strong argument when the increment of
  "more" isn't large.

  When introducing backward-incompatible behavior
  maybe other, stronger arguments would help.
