Thanks!

Bastien, could you please check the FSF record.

You are probably right. `concat' does not heart anyway.

Should not be a big deal to keep the require inside.

I tried to test your patch on various Emacs versions.
`with-connection-local-variables' is not yet available in Emacs 26.
Emacs 26 has `with-connection-local-profiles' though I am not sure if it
is a full equivalent. If not, you may need to create a compatibility
wrapper for Emacs 26.
