I don't think the relevant condition for removing such a wrapper is "after 
the CET kernel interface has been committed into the public kernel".  It's 
after we require kernel headers recent enough to have that interface, 
which may well be several years away.  Once the interface has been 
committed into the public kernel, the wrapper should be updated to name 
the kernel version that has it and to say it should be removed once we 
require kernel headers at least that recent.
