Well, an "HTTPS proxy" doesn't have to be a TLS interception device.
When I think "HTTPS proxy", I think of an ordinary HTTP proxy using the
CONNECT method to support TLS. In that case, the proxy does not get to
see plaintext, which includes the path part of the URL. The proxy can
tell what domain name you are connecting to, but not what document you
are requesting.

In either case, there's no benefit to obfuscating the download names.
