I imagine something like that, but scope does matter. It's been like a week since classic launched. Before they start taking a sledgehammer to a multi-million dollar game, they're going to want to get as much data as possible. Pretty much every MMO usually follows the same pattern
1) Unless the flaws are massive, usually minor / medium level flaws are overlooked initially because the game is new and novel
2) Majority of core content is expended. Large percentage of the playerbase is now at maximum level. Available content is limited and very frequently time gated (ie, raid lockouts)
3) Playerbase begins to get bored, the minor / medium level flaws now loom much larger. QoL changes are demanded, additional content is demanded.
WoW classic is sort of like MMO time travel. In theory we know the content and QoL changes to come, but human memory is imperfect. We tend to forget a lot of the shitty stuff and remember mostly the good stuff when we look back at the past (especially our childhood). Granted, we don't forget the really shitty stuff/trauma, but we tend to forget the smaller things. Like if you time traveled back to the 80s, you'd suddenly remember that there is no readily available GPS for easy directions, or no widely available internet with the knowledge of the world at your fingertips, or less places accepted credit cards for payment and realize what a fucking pain in the ass that actually is.
