Perhaps that's the solution: a new lvm.conf/cmdline parm that permits
independent log placement.

Allocation is initially performed the same as currently.
But if it fails and this new setting was chosen, then the allocation is
re-attempted without the log, and if that succeeds, an independent
attempt is made to allocate the log.
