The main benefit, AFAIU, is to use the system's execution units more
efficiently by off-loading some of the CPU-intensive work to another
Emacs process.

I'm surprised.  How large are memory footprints of "other LSP language
servers", and how large do you envision the footprint of Emacs-based
server to be?  Emacs has ceased to be THE memory hog long ago, it's
actually quite modest in its memory requirements nowadays.  So I don't
see why this particular job would require Emacs to become such a
memory-hungry application.

I think the time to start is not very important, since it happens
once.
