It did but apart from allowing the compilation of the code and enabling the --curl option to do something, it had no impact on the default runtime.

Yes this is confusing. In the current state, even if build against a curl version supporting imap, curl is not used by default at runtime (unless OpenSSL was not available). This patch changes this behavior.

I think the idea for this was that curl should be used when curl is available and OpenSSL is not (curl being the only solution for secured authentication in this case)

As said before, the goal of this patch is to enable curl by default at runtime when it has been "enabled" at compile time. I'll reword
Is something like this clearer ?

imap-send: use curl by default when possible
Set curl as the runtime default when it is available.
When linked against older curl versions (< 7_34_0) or without curl,
use the legacy imap implementation.
The goal is to validate feature parity between the legacy and
the curl implementation, deprecate the legacy implementation
later on and in the long term, hopefully drop it altogether.
