Maybe, but if I was maintaining PHP or another critical software, I’d think twice about letting Chainguard have inside information.

I would let Chainguard deal with the patches post official release like all other unreliable parties.

A weird take.

As a customer, I'd immediately assume no one in the security community would trust them again, and seek someone else to give my money to. Why pay a) an untrustworthy company who b) now is not trusted by anyone and c) won't ever be able to early release again anyhow? And if anything, are left out of important conversations.

Way to burn bridges. You only get to be an asshat once.
