I'm not sure of the current state of whether grep tries to use RRI on all systems or only on systems where it relies on gnulib's regcomp instead of libc.
As I recall, grep doesn't make any special effort to use RRI. That is, if the underlying library uses RRI, then grep does so as well; otherwise it doesn't.
