NOOOO! This will actually make the things even worse - looks like devs have either missunderstood the issue or are simply ingnoring it.
I think you've missed the crucial point in the previous section of that post:

We are currently working to address the below additions to the gear set feature in patch 2.2.

•Addition of the below data to the gear set information saved
•Materia status for each piece of equipment
*Amount, type, melding order
If the gear set holds this information, presumably they can match the item exactly? My understanding of the point you quoted was that where an exact match isn't available, the most melded piece will be picked first.
