Currently the logic of boot has a lot of per-snap-type cheks in the exported functions. Going forwards into core20 we know these checks are going to get more involved, so now is a good time to switch things around so that different implementations exist for each of the situations, and thus the checks can be done while looking up which implementation to use, instead of in each of the functions.
