We should try to fix this, once and for all. Some suggestions follow.
- Remove old, Blaze, PDP page (should be done regardless)
- Maybe disallow revision control from being disabled completely
- Get rid of collection observables in publications in favor of doing that on client side, return multiple cursors from those publications instead.
- GraphQL / Catalog collection to piece things together
- Change how revision control works

Should never happen
