Disable discussions "edit"

I’m wondering if there is a simple way to disable the ability to edit “discussions” in the editorial workflow of OJS 3.x once they have been sent/posted.

Before you ask why, the reason is that we would like to have an honest, transparent and time-stamped correspondence flow among authors, reviewers and editors, in which no one can withdraw his/her words by just editing and old message because it is possible.

A simple tweak to make disappear the “Edit” button would be enough.
