I'd like to be able to pass a parameter to the {% cache %} tag — something like {% cache lazyrebuild %} which would immediately return the cached version, but off in a task on the backend, it’d be rebuilding the data in the cache tag pair if it was invalidated due to an Element contained within it that changed.

This allows the front-end to always be responsive to the user, but also kicks off the rebuilding of the cache.

Absolutely agree, so what you're saying is that when the entry within a cache is saved, the cache is then regenerated automatically in the background as a task. Therefore not putting the load on the user who next visits the page and has to wait a long time for the database query to run.

This would be very useful when working with large datasets. We have a map with over 1,000 Entries plotted on it, and it takes 30s+ to generate the initial cache result.
