I believe this is considered as breaking backward compatibility. How
about creating a symlink in linux-firmware instead.

OnePlus is not supported in linux-firmware.

See discussion here:

https://lore.kernel.org/linux-arm-msm/CAO9ioeW9=TPde4P=AOcQANvPv90K-9MkcRRgb7HNwe8KiOpFjQ@mail.gmail.com/

I understood the conclusion was "let's do it".

We have more-less 3 consumers here,
  - postmarketOS (Alpine)
  - Mobian (Debian)
  - NixOS Mobile (NixOS)

some of these using droid-juicer, which can be easily updated to update 
paths.

Indeed, it is a very gray zone. There is slight difference: firmware
loading can go through the userspace, which can provide backwards
compatibility (in form of fw helper, symlinks or any other ways).

So, yes, we break compatibility, but it is documented so and it can be
handled. Compare that with the e.g. updated driver rejecting old
bindings and thus becoming incompatible with the old DT.  This can't be
worked around in any way.
