When rewriting apps, people have a tendency to say: "well, Oldversion provides X. We could make a Newversion that provides X better, but that's hard so maybe X is actually bad? We should provide Y instead." Then they're confused when nobody with X needs wants to use Newversion.
It's OK to use X until Wayland has support for the missing features. I don't really care what I'm running. But it's clear that X is not in shape to see significant development (e.g. to support new needs) in the coming decades.
