"Last a year or two"? I'll be (extremely pleasantly) surprised if Toady actually even touches the winners of last year's ESV within two years, since he's got enough to last three to six years on the Adventurer stuff, alone (seriously, look at that devpage, the ESV winners are a tiny little speedbump down near the bottom of the page, and the page keeps getting more stuff added to it). The Caravan Arc stuff is going to take something like four to six months to get through the nine "short term" releases.
After the year and a half of wait for 31.01 to come out, it's taken about 9 months of nothing but bugfix releases for Toady to actually start working on adding something new into the game again. (And people are complaining that he has put stuff into the game again, since they still want him bugfixing.)
We need that Hauling rewrite desperately.
But again, this just underlines why nobody's going to bother to do anything with the ESV. It doesn't matter at all. The same things are going to be in the same positions five years from now, and who knows if they'll even be done by then.
Things like bees get put in because they're fast and simple and don't really do anything. Things like hauling that are hard to code get shoved to the back of the line.
If you actually want your suggestions to get to the top of the list, and for Toady to work on it just because it's popular, then pull up a chair and smoke 'em if you've got 'em, it's gonna be a looooooooong wait. This is a very long-term game we are dealing with.
