If we did this everywhere we'd have hundreds of libraries in the
kernel tree and I would feel bad for all the distros that have to deal
with packaging such a thing :(

It is great for development but I'm not sure mono-repo directions are
so good for the overall ecosystem.

I understood perf had a special reason to be in the kernel tree? I
don't think there is any special here beyond it is new.
