Seems like the dev team has a good sense of humor!
Despite repeated polite requests to not ask us for specific feature ETAs, the questions kept coming. In an effort to try and curtail this, we toyed with setting a “minimum” date for the feature and simply doubling it every time the question was asked. This very quickly led to the date being after the predicted heat death of the universe. We fell back on a tried and tested response pioneered by id Software; DP Alt Mode will be done when it’s done.
