I had a vague memory that some standard or "best practice" guideline somewhere said the server should send the chain up to but not including the root, but I don't know what that might have been.
Inclusion of the self-signed root is harmless. The only case that
I know of where this is actually necessary is with DANE-TA(2) when
the TLSA RRset has a hash of the trusted root cert or public key.
