Our users are asking why they can’t remove a like after the `post undo action window mins` has passed, and I find I don’t have a good answer for them. I’d be curious to know why this choice was made before I change the default value? I’ve grown to trust the default Discourse settings as sensible, experience-based values so I’m reluctant to tinker with them without understanding the consequences first.
Are there any risks when I set this to a high value?
Thanks!

You can pretty effectively grief people by liking and un-liking forever. You could also get mad at someone and rage-unlike all their posts. In general unlimited user actions are dangerous as a rule.
