Agreed.  I think the way forward is to restructure the code so
desktop.el can use savehist-mode (e.g. so it can tell it where/when to
save the history).

There's a similar issue with saveplace.el (again, with slightly
different semantic but no good reason why saveplace.el can't provide the
needed flexibility for desktop.el to use it and let the user choose
between the usual desktop.el semantics or the usual saveplace.el
