I think you are right, but I don't think the problem is bigger than it
can be solved over time. IMO putting the independent arguments first
and dependent ones later should be the way to go in the future.

I'm not sure I'm following you -- why parsing it? In this case we are
asking the user for the options?

It's not that mandatory at all. If it is not defined you will just be
asked about options like you do today. So this won't break anything.

Unless someone decides to put something completely different into the
LaTeX-<package>-options symbol (for what i know nobody does that
today). Maybe the symbol could be called something else that is not as
likely to be used by others -- maybe LaTeX-<package>-package-options?

I will definitely look into this before committing this.

Thanks very much for your comments!
