Please see the discussion at https://github.com/awcodes/filament-tiptap-editor/pull/424.

I'm not totally against including in core but I'm not currently onboard maintaining support for spatie's package as I don't personally use it and have personal feelings against its ease of use.

With that said, it's kind of the point of allowing for swapping out the media action via the config.

I am ok with you releasing it as a "plugin" / add on or package though.

I'm just not willing to take on / inherit the maintenance burden of something I'm not totally behind at the moment.
