I think this isn't a good approach to convince the arm64 maintainer.
This change is not really optional for the Raspberry Pi 5 and possible
users/testers/CI rely on a working default configuration.

So my first suggestion would be to provide a scripts/bloat-o-meter
output (before/after). Based on this the maintainer can better decided.

In case this change is still rejected, we still have the option of
something like this [1]

Best regards
