It'd be great if eglot.el went into core, of course, and I'd welcome the
additional level of scrutiny that usually brings. However, if it does
come to that, and since Emacs 27 is reasonably distant, I'd like to keep
distributing for Emacs 26 and developing outside Emacs or in parallel
with it for at least some time.

Depends on where you draw the line, but if you really do want LSP to be
in core, then you need the full eglot.el, which has (almost) no
language-specific code. If you just want JSON-RPC support in Emacs (for
whichever other applications that might use it), then you only need a
part of eglot.el. Regardless of which parts make it into core, a
json-rpc.el could be easily be extracted out of eglot.el if it is deemed
useful.
