Correct. Indeed, it is possible to use the command \foreignlanguage or
its environment version (otherlanguage*) without having to
declare the language previously. I would say that \foreignlanguage is a
command that covers a high percentage of use cases in multilingual
documents, since it is intended for short fragments of text and only
loads the hyphen rules of the host language.

I think it is related to the previous paragraph: "I am very interested
in all possible improvements in babel so that it integrates as best as
possible with automatically generated files[...]"

I agree. I even think it would be a good point to also include the
vernacular name of each language.

By the way, Javier has also told me that he is going to consider the
'onchar=ids fonts' issue related to the case of several languages that
use the same script (already discussed here in past messages).
