Love this idea!

Hey Rob, Let me jump in. It's currently designed this way for performance. Can you imagine the complexity to look up all the events "on the fly" for each event and check all the restrictions for each logged-in member? This system would be under a very heavy load to do that. We do have a feature coming in our next release to allow you to convert a dynamic group into a static group to make this easier. We may look at this in the future, but right now, we plan on leaving this at the static groups for now.

Thanks!

Julie,

We are currently working on Age restrictions for Memberships.  I have merged your idea into the one we are already have In Development.  This will be released in early 2022!
