MarsSeed [1] filed a deletion request for gmat [2]: Unmaintained, broken niche scientific package, 0 votes, maintainer unresponsive since at least 2023-06. AUR packages have to be useful for more than a few people. This does not seem to be of any interest to anyone apart from maintainer, and even he is MIA.
