Cached languages outlasting version upgrades? about entity-explosion HOT 2 OPEN

As I wrote on Wikidata, I think the cache should be cleared even if there’s no version upgrade for some time (or maybe not used at all), as not only query changes make the cache invalid, but also edits to Wikidata. It’s not that huge amount of data, I don’t think the cache should last longer than a few hours at most.

Also, whatever method you choose, make sure not to crash if you get the old format—since this cache never expires, there may be users with the old format for an indefinite amount of time. (For example, users like me who have the extension installed but disabled for months or even years.)
