My main concern is its a really weird corner case for the grammar to remember for tuple sections and it does have very weird grammar specification issues.

I really have no objection to it for the other cases. It'd make export lists cleaner, maybe a few other cases, but how often can you really say you can meaningfully comment out one field of a tuple have have the surrounding code make any sense?

Multiline tuples don't seem all that common, so +1 on that from me.
