Because it uses ESMTP option negotiation to find out if the server
supports that.

Can you suggest an application where that would be useful? I use VERP
all the time and I can't ever recall a situation where the default
form of VERP wasn't entirely adequate. Adding features because
someone might want them for some unknown purpose leads to bloatware.
