The biggest issue is if you can't trust a guy to keep working on one game, it hurts his chances of being supported on another project. Melody and DMD are a special case, as with some creators, because Patreon kinda forced them to pick a new project without "incest". But the are still finishing DMD just at 1/3rd speed.
Its interesting if this guy, did or didnt give a reason or plan. You kinda wanna keep your supporters in the loop so they don't panic.
Though I would like to say, looking at his Patreon, it looks like they guy is still working on this in Tandem with the Pandora project.
