It would also be great to have the ability to reuse Matrix fields. This may be a bug report or a feature request, depending on the intended behaviour. Feel free to update the tags.

Hi, thanks for reaching out! This is expected behaviour.

As per Brandon's comment here: https://github.com/craftcms/cms/issues/14237#issuecomment-1915632814, only fields that store content in the content table are reusable within a field layout.

I've seen this come up a few times. Maybe there's a better UX solution, such as keeping the field in the list, but graying it out and having a tooltip explaining why it can't be reused.
