It'd be loads better if application logic were directly responsible for
making these sort of policy decisions regarding what cached resource to use
under what circumstance. Obscure least-common-denominator rules baked into
the user agent with even more obscure ways to override that
least-common-denominator behavior just isn't working out very well.

And in some other developers opinion, that would defeat efforts to make the
client resilient to 5xx errors.
