We're currently thinking about bringing our clients into our Phabricator install, the one major issue being that we have a lot of "Amusing" task statuses in maniphest. (For instance 'Scorchio'[1] for High and 'Normil'[2] for Normal).
One thing I've been thinking of doing is having a "Silly" and a "Sensible" translation that can be enabled in the User Preferences.
As the task statuses don't run through pht, I'm guessing this isn't possible?
