na.rm is a argument name, na.omit a function, na.action an attribute. They are not the same thing.
Anyway, you're right with respect to the lack of standard way. One thing I personally find most annoying is function naming. Some functions use the dot convention (do.this), some use camel case (doThis), some use underscores (do_this) etc. And what is most annyoing: this is even true for novel functions that were just introduced in recent releases.
