I used the mattduck/gh2md tool for that purpose.
It employs https://api.github.com/graphql, so I had to generate

Currently GrapheneOS doesn't have it.

The corresponding checks have been developed.

1. Don't add an exception to normalize_cmdline_options() since strtobool()
is used for kpti

2. Use new '0' check of 'is not off'
