I feel that
I'm not sure why it wouldn't work with the mission launcher for some custom campaigns. some require the new exe, like Flippy's or mine, and some move the old exe into place in the latest mission launcher update, like feda, but surely the average vanilla custom mission shooould be able to work with the exe that has build queues
maybe the build queues patch was created back before the mission launcher, so it doesn't have some vital exe functions that were added in a later update? Cm would know better than I on this, and he says it doesn't work, so I'd take his word for it
perhaps someday we'll be able to get the build queues available for more maps, but it's nice to at least see a dunemaster install with the build queues patch made available again it's been totally out of commission for a while. not anymore, it would seem!
