Will things be slower than native ostree? I've got no problem with the capability being added, but I do wonder, Why not rojig, aka native RPMs plus a special metadata RPM, aka jigdo for ostree? We've already got great RPM infrastructure. Plus we could get rid of countme.timer and instead ride the rpm-md connection like the RPM-based variants do.
