Comment (by danielbachhuber):

 Thanks @rmccue, those examples were quite helpful.

 For the next person to run into this, here's [https://github.com/lcache
 /wp-lcache/pull/97 WP LCache's implementation (with tests)]. I didn't find
 splitting `alloptions` to be horrible, but having to keep record of the
 `alloptions` keys in a separate cache does seem a bit dodgy.

 So it's mentioned, WP LCache doesn't absolutely need to have a multi get
 implementation because most cache gets will be hitting its L1 cache
 (APCu). Other drop-ins will need to implement multi get as well to
 mitigate the performance impact of introducing hundreds of new cache keys.
