I changed the component by mistake and then changed back. Sorry for the noise.

No, I don't. Sooner or later a maintainer will probably attend to it, that's
all I can say.

The usual way we deal with this is to use some mechanism to probe for the
platform in question and use an IFUNC handler to switch to the optimized
version for this platform only.
I'm not sure if 32-bit Arm platform variants can be identified easily at the
CPU level or from the auxiliary vector. It may be necessary to do some kernel
work first.
