Atlassian tends to add features to bitbucket silently, without asking users if they want one, or even adding some way to opt out.
Notable examples: 1. Auto-updating pull requests https://bitbucket.org/site/master/issues/9361/add-an-option-to-turn-off-pull-request 2. "create pull request message" when pushing to bitbucket repo https://bitbucket.org/site/master/issues/11409/revert-modify-create-pull-request-message
Even more, Atlassian staff tends to ignore any complains from users.
So it would be really nice for dev team to turn to users with their faces
