that only non-Wikimedia developers have maintained LQT is false, as a brief review of the commit log will show.
I said "non-Wikimedia users". Not sure what log you've been looking to, but I did `git log --no-merges -- . ':(exclude)i18n'` and I confirm what I said. The only exception I found so far is T104421 where you fixed a fatal (thanks!). Other than that the only bug fixes I see are some in Flow migration.
