The TinyMCE editor has an ecosystem of plugins outside of the ones included by default in Moodle LMS. This will likley grow over time. Many of these plugins will be "self contained" that is only require the Javascript based TinyMCE plugin code.

Moodle administrators should be able to directly add these plugins to their Moodle instance via the User Interface. This also means developers won't need to write additional Moodle code for some plugins.

Note: This approach may not be suitable for all TinyMCE plugins such as those that connect to an external service and require configuration per instance.
