I'm a practitioner, I've managed bug bounties for several companies, and spent 15 of the last 20 years doing assessment work almost exclusively, and nobody takes CVSS seriously. It doesn't say anything to point out that some people structure "bounty tables" based on CVSS, because, as I said, it's a ouija board; the actual rules for what bugs are worth are still
ad hoc, they're just used to determine the CVSS instead of the price directly. And that's not a super common practice!
CVSS scores are put into audit reports --- at the ouiji levels clients want --- to shut up the suits in compliance.
