Seem sensible, and feel free to push, please.

But it'd also be nice to have a backtrace to that error to
see why jsonrpc.el is trying to access the jsonrpc--events-buffer
"too early".

And kudos for going through these EIEIO bugs, even if in backward
incompatible ways ;-).  Accessor functions definitely must go thru
the slot-value protocol.
