I think we can most certainly just try increasing the minimum version to 5.1 in the next merge window and see.

Yes. The arm64 issue is a clear and known bug, plus I suspect gcc-4.9 is ridiculously old in the arm64 ecosystem anyway.
So the arm64 issue is a bug-fix, the follow-up of just upgrading gcc requirements in general would be a "keep up with the times, and allow those variable declarations in loops".
