Thanks!
I've been using plocate actively for a while now, I am yet to encounter any issues. They do not have a test suite so I can't really measure coverage or run tests, though. Outside of that, the package appears to be stable, minimal changes happen between versions, implying that the project is likely in a "complete" state, where no further features or expansions will be added, but I haven't checked that with upstream.
