a821 [1] filed a deletion request for gtm [2]: Orphan, out of date for more than 5 years, last updated in 2016. The PKGBUILD does not follow current GO guidelines and is in very bad shape; someone would need to rewrite it, but upstream [0] seems inactive (last commit in 2019), so not sure if it's worth it. There is `gtm-bin` elsewhere in the AUR. I think it can be deleted.
