AFAIK none, but not for that reason: it seems to already be implemented and
part of the aarch64 abi. It would be helpfulmfornthe change request to
confirm this.

For the python code, also none because it will also be implemented as
default via upstream in python 3.12 and thus coming to fedora even without
this change request.

So the situation will be that the slowest mainstream arch and the slowest
mainstream code on all arches will have frame pointers enabled, but not on
the fastest arch for the fastest code.
