I'm not advocating complexity.  I'm advocating using the same APIs as
the rest of the kernel, for doing the same functions.

I don't really care about the pid namespace in this context.

I am just asking that we compare a different field in the task struct.

I am asking that we don't accumulate new users of an old crufty bug prone
API, for no good reason.

I'm asking that we don't be different for no good reason.
