In order to improve accessibility we want our editors to be able to mark part of the node title as belonging to another language. To meet that requirement we use
HTML Title →
module. This allows the accessibility requirement to be met, but the editorial UX is horrible in that they need to type in actual HTML tags with attributes. It would be much better if we could use this module to provide a specially configured editor for this. Unfortunately "string" type is not supported in _allowed_formats_field_types(). However if we add "string" type to the list of supported types and tweak allowed_formats_field_widget_form_alter() a bit, we can show the specified editor on the node title field!
Extend the list of supported field types and tweak allowed_formats_field_widget_form_alter().

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Would it not be better to add a hook so other modules could add field types?
e.g. HOOK_allowed_format_field_types
That sounds like a worthwhile but separate issue/enhancement for field types which are not in core.
For the core string field type, I can't see any reason for the module not to support it as standard.
