Description
This is from https://github.com/haikuports/haikuports/issues/4806
According to the ticket we could probably enable this for Haiku's kernel (and maybe app_server also) as well as libbe.so

Ah, I guess we don't do it for the whole system, just for the kernel. Indeed, probably we could do it for everything but libroot.so, I suppose? Or maybe more broadly still?

It only makes sense for kernel add-ons, right?

No, it makes sense for the kernel itself, too, because kernel addons do not override symbols for the kernel, only for themselves.
While libroot POSIX functions need to allow interposition, I don't think libbe ones do (indeed it mostly doesn't make sense to do that.) So we may be able to turn it on there.
We already do this for the entire system: https://xref.landonf.org/source/xref/haiku/build/jam/ArchitectureRules#345
