Well fair, but we had been using it for 4+y at the time before running into that, and the rails-based migration scripts basically never failed once despite being migrated across 6 majors and countless minors/patches. Being a small company, from that PoV it gave us very little downtime for essentially zero security work to maintain it. Of course we had daily (and tested) backups too, just in case, but we never had to use them.

Overall, the downtime of GL, even with auto-upgrading and the issues above, was perhaps 1.5 work-days across 6+ years. GH exceeded that budget in the first 2 months after migrating this year...
