No, it isn't because it requires you to send the domain portion of the URL
in clear text and it may be that you don't necessarily want to disclose even
that much information about your browsing to the public.

If you don't want even the site you are browsing public, HTTPS is not
the solution.  Without SNI, HTTPS is one-site-per-IP (nobody uses the
subjectAltName to host multiple different sites on the same IP in
practice), so all somebody has to do it fetch the certificate from the
same IP/port and look at the CN/subjectAltName.  Either that's the site
you went to, or you accepted the host/cert mismatch (and are a target
for spoofing).

I don't speak for anybody but myself - that's enough trouble.
