From what @Charlaquin who I quoted said? I thought that was obvious. She's contradicting what you're saying here.Where do you get that...? When he was pressed, he admitted yoy could mix and match, but their recommendation (which I am sure will be true at AL tables) is the new version supercedes the old.
Either you can or you can't intentionally mix. If they're going to make it so you can't, like, make it so Beyond forces you on to the new rules, for example, if you have them, then absolutely this is a huge revision to their plans and they lied previously.
If you can mix, and they just like, think you should probably use the new things - that's still a change, because that wasn't the line a year ago, or even six months ago, which was the much more open "use whichever you prefer!". But it's not as big of a change. If that's really true, presumably Beyond etc. will always let you pick the "old" version of a thing (as it does now).
