I don't get your point. Would you rather remove the option and force everyone to run their own node? What a monero rpc node learns from you is very little. Your IP, nothing else. Unless it's malicious and drops your request after you submit a tx, then if you retry immediately, it can learn which of the outputs (the only one again repeating in the ring sig) was yours. And even that is going away with FCMP++.

Have you had an IQ test lately?
