If we start with the store.el interface, we probably won’t even have
considered something like multisession.el’s interface. FWIW store.el
interface is designed independent from multisession.el, the latter
just happen to fall into a subset of store.el.

The aim of store.el is very clear: it provides a generic persistent key-value
store of Lisp values.

Putting the more specialized multisession.el interface in master means 
we will need to provide backward compatibility even if at some point
store.el is added. I don’t see any downside of the other way — providing
just store.el interface from the beginning.
