And… you really believe that? You believe that if everybody chose to love it, the Reforged chat UI would not be “less pleasant” than its 2003 Frozen Throne Battle.net chat lobby system counterpart? Really?
You are assuming that users patched along with the public game, going from 1.27 to 1.28 when the game moved all maps into Documents. What if a user upgrades directly from 1.27 to 1.32? Wouldn’t the Battle.net Launcher simply delete all of their maps?
Maybe the guy you were talking to is someone who faced that issue, and had all their maps deleted at some point by purchasing Reforged after not playing for a long period of time. I never confirmed what I am saying on my own, but I always assumed it was physically possible.
Edit: Random example off of Google of some user reporting exactly this issue in 2020:
