@baleine@piaille.fr nice to meet you!
Yes, it seems Guile-GI is the work of just one person who has been maintaining it for many, many years, and is probably getting tired of doing such a thankless chore. Also, there is a competing project, G-Golf, which does just as well, and is more up-to-date.
When I discovered a Guile-GI bug, others here on the Fediverse have told me that the Guile-GI maintianer does participate in discussions on the Guile mailing list, but I haven't tried contacting them about the bug yet.
