You're right, I agree.  The attached patch takes a completely
different approach: it makes it possible to override the value of
`TeX-insert-braces'.  `TeX-insert-braces' is forced to nil for
{top,mid,bottom}rule macros.  A FIXME in style/booktabs.el is also
resolved.  As a side note, I don't like very much the
`last-optional-rejected' feature, because there are cases in which the
second optional argument shouldn't be skipped if the previous one has
been rejected.

Comments about the patch?

Bye,
