Why doesn't Codeforces force the contest authors to submit both the problems and editorials when accepting a contest? It would be really helpful to be able to access the editorials right after the contest. There are cases where the authors would want to target specific mistakes done by the participants (during contest) in the editorial. But I've rarely seen such detailed editorials. Most of the time, the editorials are straightforward solutions to the problem. If that is the case, then I don't see any harm in forcing the authors to be prepared with the editorial before the contest itself.
