Of course not.

I believe this is what FreeBSD does (minus the warning part).

I am a bit ambivalent about that. I think that defaulting -R to be the
same as -L if -R is not defined, would increase complexity and confuse
the users even more. I would even go as far as to claim that it will
have negative security implications as people become sloppier about run
paths. The other side of the argument is that the naive user can use
-L most of the time and does not even need to know about -R.

Are we the only OS requiring -R?
