If you say so.

Not quite.  The rule is that a 2-letter second subtag is a country code.
Country codes could have appeared elsewhere, and may still wind up doing so
before RFC 3066 is obsoleted.

But not much.  As an advantage, country codes can always be found in the new
draft, whereas in RFC 3066 they could in principle be anywhere.

Like other people, I sometimes post when tired; I don't think this particularly
interesting.

I fail to see what this has to do with the merit of marking scripts in language
tags.  The preferred IETF charset, UTF-8, contains no information about script
whatever.

Extended language tags will neither help nor harm you, then.
