Absolutely. So many other apps like Slack have this feature as an option, not mandatory to use it.
On a Friday I finished a project after 5pm - I did not want to send the comment at that time for several reasons. I wanted to prepare the comment/response to send on Monday morning but couldn’t.
I wrote the comment anyway without sending and later got an email asking if I forgot to finish my comment… On Saturday. Talk about frustrating.
