Delete all fades but only where there is a "separation" and not an actual edit

This one is a real scripting zinger.

I have a macro that deletes all fades and heals separation. Easy enough. But what I would really like is a macro that determines whether a fade is a separation or an actual edit, and if it is an edit then it leaves the original fade as-is -- if it is a separation, it deletes the fade and heals the separation.

Note: I know how to batch create fades but I'm trying to keep the original fades where heal separation isn't healing a separation.

A little context: I am a music editor and I often get AAFs from picture editors with cuts all over the music tracks. However, 80% of these aren't actual music edits -- they are inadvertent and unnecessary cuts made while they were editing the video. Nonetheless, a lot of picture editors will auto-apply fades across their music regions, which means the AAF I'm getting is riddled with "fake" fades/edits. So I end up going through each fade, one-by-one, deleting the fade and healing separation (which unites the clips again if it's not a true edit). When I come upon a clip in which the heal separation does not unite the clips, I know that this was an actual music edit performed by the picture editor, and I know to leave the fade alone for now.

I'd like to automate this process for an entire selection.

The psuedocode for the macro I'd like is something like this:

const fades = selectAllFadesFromSelectionAndMakeArray()
fades.forEach(fade => { 
   if (batch fade dialog is 'fade in' || 'fade out') {
       break
       } else {
       deletefade()
       healseparation()
       if (a cut still remains i.e. there are still two separate clips where fade once existed) {
          undo deletefade
       }
   }
}

I realize creating an array of fades and looping through them might be nearly impossible, and that determining whether a deleted fade leaves two clips or one might also be impossible, but I wanted to check in here. There might be other methods for achieving this as well -- like shift+tabbing through each object, determining whether it is a fade or a clip (is "delete fades" menu option available), if it is a fade then delete fade, etc etc
