Reloptions in general are not used much in extensions, and one could
assume that reloptions of type real (well, double) are even less.

I make use of this API myself, for some personal stuff, and even some
internal company stuff. And I am ready to bet that it is much more
popular than its reloption cousin mainly for bgworkers. Hence a
rename would need a compatibility layer remaining around. Honestly, I
am not sure that a rename is worth it.
