The only way to find out is for that person to update.
The problem with that line of reasoning is that if Sonos force a firmware update on your speakers as part of the update then - as far as I’m aware - there is no going back. You are stuck with the result - which might work, or (as you say yourself) it might not.
Sonos do not provide any mechanism to revert to older versions of the speaker firmware (indeed, they don’t provide any mechanism to revert to older versions of the app, though there are some ways around this).
So… if the current app does what they need it to, why “upgrade”?
