re: What if we disable these caches, refresh the pages in a browser, then re-enable them? Would that reset the cache to the latest version?
Sorry, no. The caches are only updated on write events (add/edit) not read events (showing in the browser). I do plan on releasing a new tool based on the new CSV export code to do cache refreshing but this will not be done in any timeframe that will do you any good.
There just is no easy way to deal with “force refreshing” the caches at this time, sorry.
