Bullshit. The problem you seem to deliberately ignore is that once it's
in the kernel, it's impossible to eradicate. It's not just a crap design,
it's a crap design you are taking in as-is.

And no, "the sole consumer of that API knows better, so bend over" is not
a good idea. We have shitloads of examples when single-consumer APIs
turned into screaming horrors; taking that in over the objections to API
design, merely on "they do it that way, who the hell we are to say they
are wrong?" is insane.
