My experience with symbol files and C++ is: It's a nightmare.
I tried them on a few occasions only to drop them a few uploads later, as
they add a lot of maintainance burden. They will frequently break, as some
other package or toolchain might have influences, are
architecture dependent and once you think you've got it you'll get the
next breakage… I'd just override the warning and be done.
