So IIUC, this fix consists of two parts:
1) generating client_bodies_h only AFTER protocol.x for all three
drivers was processed,
2) Initializing remote_daemon_generated to remote_xxx_generated (which
contains protocol.x processing targets).
IMO, it's only the second step that's really needed, isn't it? I'm not
against this patch, I'm just trying to confirm I understood the problem
and the fix.
