 > Curious, since you've already debugged this issue if you found any
 workarounds in the mean time?

 For the customer this affects, we worked around it at a higher level -
 i.e. we avoided calling `get_option()` for the missing options in places
 where we have a high volume of calls.

 The overall increase in cache traffic is observable across multiple
 customers who upgraded, but we also have this mitigated to some extent by
 caching misses in a different caching drop-in that we use on other
 customers. (That alternative caching drop-in knows when a cache miss is
 invalidated by a cache set elsewhere, so it's safer to do so.)
