Thank you for the explanation.  I don't think it's a good idea to add
a `(TeX-insert-macro "usepackage")' in that case, because most
non-trivial documents require more than one package to be loaded and
with different options (so can't be loaded with a single
`\usepackage{pkg1,pkg2,pkg3,...}', think about `fontenc', `inputenc'
and `babel').  AUCTeX cannot foresee when should stop inserting a new
`usepackage' and prompting for a new package until an empty input is
reached isn't feasible with the current implementation of
`LaTeX-arg-usepackage'.

In my opinion, the way to go in this case is to use a template.  Some
months ago I sent to the list a patch adding built-in support for
template (ie, without relying on external tools like autotype
skeletons), but I got no reply:
