Correct (kind of)... We do have a migration tool so that anyone who has created products already on our site will be able to migrate them to the new version.
A while ago, 4 of the marketplacee projects came together and agreed on a rewrite of the nip-99 and created an extension to it.
You can see it here: https://github.com/GammaMarkets
As I said though I am open to providing a way to making it backwardly compatible. This is also a function that someone else might build as a plugin to the Plebeian solution since we will be opening up an app/plugin marketplace.
