Yes, but I was addressing your comment that more than 4 bones per vertex was in 3DGS Pro's future. It isn't an experimental or beta feature anymore, it's an official one. It's true that you can't edit these bones in MED nor will the animation editor display them, but you didn't' mention that. Hopefully, this will change in a future update. However, most people aren't going to use MED to edit their FBX files anyway, so it doesn't really matter.

fragMotion will support FBX soon and up to 4 per vertex, and fragmo is aware of the recent changes and the upgrade to A7. The creators of Ultimate Unwrap 3D are also aware of the new MDL7 SDK and FBX support, too.
