It's not 'negative' it's just kind of unpredictable.
The problem is that the more options player has - the higher chance that something can go terribly wrong. Thus I understand why HotA team doesn't want to make any options and everything is set in stone once implemented.

So enforcing options seems to be a good solution.

For me personally, the most frustrating feature is disabled stats overflow. So I'm waiting for 1.15 as I hope you'd implement the changes we've discussed on Heroes Community, such as heroes hireability.
