While it might be useful for developers who have machines that
support multiple back-ends to load & unload - there really isn't
any credible end-user case for it - so it has a very low priority.
Perhaps zero (it would complicate the code for no useful purpose).

Even for development there's a lot of re-booting (after all, pstore
is really about saving the kernel log when the system crashes :-).
