> Capital letters are only useful as ECC, not direct signal. (You can't pronounce them, they aren't preserved in many contexts, the lay writer won't respect them, etc).

In speech I clarify if and when needed, naturally.

> Your idea is like saying "Google" can be a trademark owned by Alphabet but "google" is just a verb. It seems like a cute linguistic hack but won't be meaningful in the public discourse.

You have it exactly backwards. Descriptively "to google" is a verb.

Descriptivism is much better than prescriptivism in natural language. Sure, we need to use prescriptivism when teaching the language, but we do get to evolve the language. That's just how it goes and has gone for the entire recorded history of mankind.
