Hooks seem more suitable for this use case, because 1) it's easier to allow complicated stuff, 2) sysadmins aren't meant to use this config option.
On gerrit there's an attempt from 2015. It's probably easier to start again from scratch, but the implementation can be copied.

Since the consequences system is being refactored, it's probably a good idea to write this hook afterwards. This hook might be used as a single place to register both the extension name (currently done via $wgAbuseFilterActions) and the "callback" using the new system (e.g. by returning a value object extending Consequence as per r633380).

This was implemented last month. The config is deprecated and will be removed in 1.37.
