Adding a \skip on the fly is definitely not a simplification.

You have many ideas, but the point of barcheck is to indicate
errors. I think that it is pointless to be pedantically correct if
errors have already been detected. For the last case, I can imagine
your reasoning, but \addlyrics (and its more modern friend
\newaddlyrics) are enough of a bitch to get working without all the
fancy things.

I propose to look at this again once more pressing issues have been resolved.
