No, because it can never happen ... :-)
I think you meant to ask "does it bother anyone that some nonvalidating
parsers may accept documents that are not well-formed?" on the grounds
that detecting the WF-ness error requires reading an external entity
that's referenced (!) but is not included.

That document wouldn't be valid since it's not well formed ... but there
can be nonvalidating parsers that do not recognize that WF-ness error.

That doesn't match my understanding of the spec. Could you give an
example of a case where a validating processor does something other
than report something that a nonvalidating one won't?
