Yes - OpenBMC does this. The one mailing list supports the OpenBMC
project, and within that they deal with code for several different
components - the kernel, u-boot, etc:
They (generally!) use these subject prefixes to distinguish between
patches for different components/projects.

That's a good idea. I'll spin a v2 with that.

That's valid. I'm happy to leave 'labels' if you have designs on that
for future. How about 'prefixes'? That also works well for leaving in
version and series markers - they're all prefixes.

At the moment, no. The use case is our CI system where we want to be
able to take each patch one by one and figure out which tree to apply it
to. So we don't need to filter on categories/prefixes.
