Ok, you're right:
"The proposal provides run-time lock-free query functions rather
than compile-time constants because subsequent implementations of
a platform may upgrade locking operations with lock-free operations,
so it is common for systems to abstract such facilities behind dynamic
libraries, and we wish to leave that possiblility open. Furthermore,
we recommend that implementations without hardware atomic support use
that technique."
But that's rather an abstract and untechnical statement.
