What you call socially positive others may call execution cost. Because you might improve on a pension fund limit order. So it's best to not get into this territory.
A store where you do a query, get a result set, but also a callback (reactivity) in the future if that query would return a different result set if you were to run it again.
Imagine a "row count" HTML element which is automatically updated (reactive) when a different part of the web app inserts a row in the data store.

Are we sure that's a good idea? I've read that one of the reason for early pregnancy failure is that the embryo is not fit enough and it would be a waste of time and resources to commit to it.
Another very counterintuitive finding is that if you try to implant embryos in various tissues (brain, liver, ...), the one in which is the hardest is the uterus! Because it's actively fighting against the embryo.
