Something like that, yes.

I don't think words-include-escapes is the right thing to use, though.
I think that doing M-f on "R\(A|B\)", one would want point to move to
just after the R, not just after the A; escaped characters should be
word separators, just like -s are; they should be thought of as \\s_
rather than \\sw.

Something like `identifiers-include-escapes', maybe?
