The quote is:
The server MUST discard any knowledge
obtained from the client, such as the argument to the EHLO command,
which was not obtained from the TLS negotiation itself. The client
MUST discard any knowledge obtained from the server, such as the list
of SMTP service extensions, which was not obtained from the TLS
negotiation itself.
The argument to EHLO is just an example and is clearly not the entirety of
what the server is supposed to discard.

It is required to do so.
