I also appreciate that this is that it does not encourage prompt disclosure.

I will do my best to give positive incentive for prompt disclosure.

The things that are within my control are:

- Recognition with git authorship for patches you created.
  - See https://sourceware.org/glibc/wiki/Contribution%20checklist for how to
submit a patch and specifically the copyright requirements.

- Recognition with "Reported-by:" markup in git commit messages (if you are not
the patch author).

- Recognition with your name in the project NEWS for the release as the
reporter.

Please feel free to suggest any other actions I can take to provide incentive.

Regarding the assignment of the CVE ID, like Florian says, we're gathering
consensus on this for unreleased products.
