Oh, for sure. Reconciling a bunch of different things' ideas of what libturkey they think they need into a single image must be a nightmare. In theory, that's what BuildStream should be helping with since gnome-build-meta[1] is only going to have one of those for different components to depend on. (If there were two libturkeys, it would be very obviously wrong). But I guess the trouble then is a lot of extra apps aren't in gnome-build-meta?

When I was messing with BuildStream a while ago I found myself wishing projects put reference BuildStream elements in their own git repos, but I suppose that would get messed up in the same way.
