Comment:

 Thanks @redsnowcompany for opening this ticket. You're right, the
 `pre_cache_alloptions` filter is unusable from plugins and themes. Seems
 it can only be used from cli or from one of the caching "drop-in" plugins.
 Don't think that can be changed.

 Best would be to update the docs. A similar "too early" filter is
 `enable_loading_advanced_cache_dropin`, see
 https://developer.wordpress.org/reference/hooks/enable_loading_advanced_cache_dropin/.

 > We were having trouble with a site that loaded all of the options with
 autoload 'yes' and it crashed with a memory limit exhausted error because
 there were too many options.

 That's usually caused by old or buggy plugin(s). Best would be to fix or
 replace the plugin. Having a huge options table is no good :)
