Yes, it's that special case.  I don't believe there are many packages
sharing the same options, but it's possible in principle, I verified
it with handcrafted packages.

I'm not sure I understood what you mean.  In the patch,
`LaTeX-arg-usepackage-get-packages-options' (or its new name) prompts
for a list of packages (one or more) and their options, so
`\usepackage' is inserted as

    \usepackage[options]{pkg1,pkg2,pkg3}

You are suggesting to prompt for packages, and if one supplies more
than one package s/he will be asked for options for each package,
separately, so they'll be inserted as you showed above, is it correct?
 In this case, I think that if one wants to load different packages
with different options s/he should call `LaTeX-arg-usepackage' (ie,
`C-c RET usepackage RET') many times, or use the new
`LaTeX-insert-usepackages' which makes insertion of many
`\usepackage's easy.  That's because I often load many packages with a
single `\usepackage' if no option is needed and I think it's a quite
common practice, so I like that packages are read with
`TeX-completing-read-multiple'.

Bye,
