No, they are not deprecated.  Presumably they are not mentioned
because they are not available in some Emacs terminal sessions.

That doesn't mean we shouldn't mention them - we should just
point out that they might not be available in some contexts.

They are particularly handy if you are using prefix args
a lot or repetitively, as they use the same modifier as `C-u'.
And they are somewhat easier for some people to type on some
(common) keyboards.
