I am referring to this part of the documentation:

    --no-curl::
            Talk to the IMAP server using git's own IMAP routines instead of
            using libcurl.  Ignored if Git was built with the NO_OPENSSL option
            set.

So when built with openssl and libcURL, we used to have a feature
that allowed to bypass cURL by passing --no-curl for whatever reason
the user chooses to avoid cURL.  This patch discards that option,
doesn't it?

Maybe such an optional feature may not be very useful, but it should
be explained and defended in the proposed log message, and it also
sounds like an orthogonal change to always require libcURL.
