The topic of "What is going on with Liquid Threads?" has popped up again[0]. I've said that I think it should be considered to be in maintenance mode. My reasoning:
* It isn't under active development, but * It gets quite a workout on the MW.o Support Desk (and other places on WMF sites)
I'm fairly confident that, as a result of it being used in such a public way, we'll be able to find someone to fix problems or at least have the motivation to fix any problems that come up ourselves.
That is, I think it is safe to say LQT will remain usable in its current state on any coming MW versions for the foreseeable future.
Of course, if someone wanted to start driving new development on it, that would be great.
Right now, though, all I'm looking for is a confirmation that it will remain usable. I imagine one of the first things that we would need to do is include it in some testing plans.
