Alleged? By whom? When? [etc.]

Exactly right. Hence, there is some grey area, due to the vagueness of "alleged". At least we agree on that point.

The problem with not intelligently differentiating between missing features and bugs, is that it makes it impossible to prioritise properly.
A bug is (should be) a higher priority...
A missing feature is lower priority...

That's not particularly controversial, but it presumes that "bug" and "missing feature" can always, necessarily, be differentiated. I.e. it's premised upon you being right when you say "a missing feature is not a bug."

And that pretty much addresses your "dependant [sic] feature" argument.

It wasn't an argument, it was a mere observation.
