That's why Privoxy can randomize the time within ranges that
are unlikely to cause revalidation failures:

Note however, that using If-Modified-Since as Cookie replacement

Therefore it's questionable if anyone is going to bother.
Especially since the latter can't be easily fooled without
purging the cache.
