The connection lies in the Mailer interface: Every inset that needs to pass
data between kernel and frontend has a mailer, and this mailer exchanges
the data in the same format that is used in .lyx files and naturally uses
the same classes to read and write this data (in this case
InsetCommandParams). Since the inset name is part of the mailer interface
you would need a new mailer and a new controller if you changed the inset
name to individual names. Maybe it would also be possible to change
InsetCommandMailer to recognize the other names. I don't think so, but I do
remember this only vaguely.

Yes, some insets already have their own controller, but currently that is

That's what always happens with compatibility layers: You can write in big
red letters not to use them for new stuff, but if they exist they get used.

The most important ones should probably be handled individually, but for the
not so important ones it should be simple, e.g. a listbox and a text edit:
The listbox contains all argument names, and if you select one the
corresponding value appears in the text edit. The only problem with this
approach is that in some cases there is a difference between an empty
parameter and a parameter that is not given at all. But this could be
solved with two listboxes: Onwe contains all possible parameters , and the
other one contains the selected ones (similar to the citation dialog).
If you want to be really fancy you could associate a type to each parameter
(string, integer, LaTeX length etc), and instead of a text edit the input
field would change dynamically to a sepcialized one for that type.
