ABI issues do not concern upstream. And that coming from me working at a
company who dance a lot to make ABI happy.

Also, I'm missing the reasoning why you use the ABI as an argument at
all: do you know of a particular case where people are thinking of
backporting this or this is all hypothetical.

Not really - normally, when you fix ABI issues with symbols
disappearing, all of a sudden, you add dummy ones so that the ABI
checker is happy.
