Comment (by flixos90):

 @spacedmonkey While the `wp_cache_themes_persistently` allows filtering
 the expiration, it primarily allows making the `themes` cache group
 persistent, so we'll probably have to decouple this and use a new filter,
 as this one does something else at the same time.

 Regarding cron cache invalidation, I don't believe this would be useful,
 given we'll put an expiration of 30 minutes on those caches anyway.

 On another note: This discussion prompted me to build a small and simple
 plugin to flush transients (most relevant for sites that don't use a
 persistent object cache): https://github.com/felixarntz/flush-transients

 This would be a simple solution for sites without a persistent object
 cache that would want to have changes immediately reflected after a
 deployment of a theme.
