Make Custom Fields on subtasks optional

This is a terrible update. It just adds confusion to sub-tasks, increasing clutter (every one of our sub-tasks now has 8 useless fields on it), and I can’t believe this wasn’t tested before it rolled out to everyone.

The worst part for our team is that the new show sub-tasks in list view feature, which started this mess, ruins the sum feature, because it can’t calculate a total for more than tasks with more than 30 sub-tasks. I’m just trying to plan sprint capacity and the ‘sum’ feature is really not that hard to get right. Features like this need to be implemented with far more care.
