Problem or Use Case

I'm opening an issue for listing my extension.

https://github.com/mehrnet/fossbilling-registrar-porkbun/

Proposed Solution

since this was added to the repo's readme:

Extension submission is currently paused while self-service submission and management are being prepared.

If you maintain an extension and would like it to be listed, please open an issue in this repository with a link to the extension and any relevant installation details.

I'm opening this issue here for further actions since the original PR is now completely irrelevant.
