An ability to edit and delete ALL the comments (BB-9845)

Why we're limited to being able to edit / delete only our own comments? And we can't do the same on auto-generated comments?

At least give us ability to delete them or to stop them from appearing!

I can't count how many issues were only partially solved by me, because I missed something important, added in a comment, because this comment was surrounded by many useless, not-editable, not-removable, auto-generated comments, added after each edit to main issue text, after changing a milestone, component, priority, kind, assignee etc.

Let's face the facts: In current BitBucket's implementation, auto-generated comments are completely useless and yet you didn't give us any solution to get rid of them!
