so does the implementation do that?
can you prove it in all cases?
what will break if we just change it without knowing?
after all, it has been 15 years to come across a botched receiver's implementation
of PSH (ie, godaddy's) which is the only reason to change it.
that's what i was pointing out. i could do the work myself, i suppose, but i haven't got the incentive.

i suspect arguments like that caused the current situation with HTML, CSS and Javascript.
computing is needlessly regressing.
