I know what you mean but requiring people to have at least a little
Scheme code/issues in some GitHub or GitLab projects is not a very high
bar. It doesn't have to be a big amount.

In all security matters we should keep in mind that Scheme.org sysadmins
are volunteers. That means we can't do audits and respond to incidents
as well as a good commercial company would. Some caution and
conservative design is preferable for that reason.
