 Hi,

 I am using https://github.com/tillkruss/redis-cache as a Redis adapter and
 a persistent object cache plugin. I would like to cache "counts" cache
 group in Redis as well but even if I remove it from non persistent groups
 in redis-cache Wordprpress adds it back in
 https://core.trac.wordpress.org/browser/branches/5.2/src/wp-
 includes/load.php#L586. Commenting out this line solves the problem but it
 is not a solution and I cannot find any way of disabling this default
 WordPress behaviour.

 It looks like a bug that whenever object-cache dropin defines
 wp_cache_add_global_groups() function (like redis-cache does) it is
 impossible to remove "counts" and "plugins" from non persistent cache
 groups.
