Ah!

I knew I had seen that, somewhere, and git agrees with me :-)

commit 1ec984b154aa3247ef58c9d44e7e477880b632b1

    Add SSL library version reporting.

    SSL library version is also sent as IV_SSL=<version> to the server if
    --push-peer-info is enabled.

... but unless explicitly permitted, we only send a limited set - nothing
that could be used against the client (like, SSL library / vulnerabilities,
or MAC addresses).
