Comment (by convissor):

 Replying to [comment:7 ryan]:
 > wp_cache_reset() was only ever implemented by the default, built-in
 cache. The other backends did not implement it. Now that we have
 switch_to_blog() it is even more useless since core never calls it.

 Deprecating  and removing the reset methods is fine.  Even if the reset
 method was never used anywhere inside WP's core, the method was there for
 the general public to use.  And they have, I'm living proof.

 The existing deprecation messages point people to the
 {{{switch_to_blog()}}} method, but that method does not clear the cache.

 The deprecation messages needs to be updated, please, to point people to a
 proper replacement: {{{flush()}}}.
