Definitely.  Would you like to give it a try?

Well, that's not how we document such functions, right?  Both the
effect of the argument, when used from Lisp, and the fact that it's
the prefix argument in interactive invocation, should be stated.

No, it's definitely not a no-op.  It is only a no-op if the previous
non-blank line has no white space at its beginning, or the current
column is already past that first indentation point.  IOW,
indent-relative-maybe only ever indents to the first indentation
point, and only when that indentation point is preceded by whitespace.
