I personally always remove my username from the auto-generated clone URL for HTTPS because I want to share links to files, commits and branches directly from my IDE, VS/Code, and those links need to not include my username; the IDE extensions I've used, take the remote URL as the base of any link it generates.
Git automatically handles my username and password, so I think the username in the URL is for old git clients.
Should Bitbucket stop including the username in the auto-generated clone URL?
