Use "www." instead of "http://" doesn't make sense

Problem/Motivation

The option to always replace http:// or https:// to www. doesn't make any sense to me. E.g. if you want to shorten an URL that lives on a subdomain https://blog.example.com it would become www.blog.example.com which is not valid.

Steps to reproduce

See above

Proposed resolution

A. Completely remove this logic
B. Make the logic smart to only strip http(s) from URL's that already contain "www."
C. Rework the logic and label it as "strip http(s)://" so it just does that, and doesn't prepend www.
