I think that the assumptions that it makes about the ability to cache the
output, and apply to every transformation or every function may be a bit
optimistic.
I would have it off by default but put it in the tuning guide, with
something written up about the circumstance where it will work and the
circumstances where it will not.
A setting the marks the return as cacheable in the configuration would be
the better option, on a per transformation basis.

> Given how important caching is in the enrichment topology, we should have
> caching for stellar field transformations in the parsers as well.
