On a previous stream we looked at encapsulating Action View template details (format, locale, and variant) in a nice class rails/rails#42210. That code is now being used for template lookups rails/rails#42945.
Today I'd like to use these template details to change how we do Action View's fragment digests.
Currently these fragments are calculated separately for each different set of details, which means it can't be done at boot and uses more memory than it needs to. I think it would be better to do the template digesting once at boot time (rather than on the first request to encounter it), which would be faster and use less memory.
