This doesn't change that, I expect you can still remove this a zipper and have another sewn on, just as before

You can, but you (or rather atelier\studio) will have to buy a special machine to do so.

If these become commonplace, so will such machines.

I hope in case of success this will be just one of the programs in your generic sewing machine.

I'm afraid YKK might not be generous
