I would use tasks for myself and the team way more often if a reminder would come through to my inbox when the task reaches it's due date. Or if the due date was still when the task needed to be done by and there was a separate "reminder" date that would alert all people on the task

Yes, please!

can't believe notifications for tasks are not a thing

Crucial!

This is a big missing feature for me - I keep missing task deadlines because I don't get reminders. I'm not checking my Tasks list all the time so a reminder is vital for me.

Yes please
