I'm afraid not. I've been trying to follow the thread these past few
days and frankly I can't think of anything beyond all the options that
have already been discussed.

I agree that the safest solution (or the least compromised, depending on
how we look at it) is to add [0pt] in all cases. I believe this should
not bring any unexpected consequences. At least I've tried all the
tabular environments related packages that I know of and there don't
seem to be any problems. And in the case of the verse package and verse
numberings, the solution is ad hoc with the patch that I have planned (I
hope to find a gap these days to finish it and test it...): The idea of
the patch is to replace the current separation between stanzas that Org
adds (\vspace) with a white line, and (only) in that case it would be
necessary to ensure that the last verse of the stanza ends in \\!.

On the other hand, if 'factory-cleaning' unnecessary instances of [0pt]
is going to be problematic, I also agree not to add that action to the
exporter. I think it would be better to leave these things up to the
users, depending on their use cases. After all, it is not difficult to
do it using a specific export filter. Maybe add some tips and examples
of basic filters in the documentation, especially for users who don't
have a lot of experience writing filters?

BTW, I also hope that one day this LaTeX problem, which has been there
for so many years, will be solved (because it should be considered a
LaTeX bug, or a LaTeX design flaw, as Maxim commented in another
message). 

Best regards,
