Fair enough, everyone has their own tastes and there is nothing wrong with that
It's also about limits of budget and space, and what alternatives you can get in that direction.
If i put 7.1 in Amazon I'll get as first result "Fluance Elite", a shitload of speakers, for about $900 new. I can count 18 individual drivers in 8 boxes some of them being floorstanders meaning a lot of wood in the package.
The 7.1 system is about $50 per driver. If you invest that $900 in a stereo product, you're ending up probably with 6 drivers on 2 3way bass reflexes, meaning $150 per driver. The quantity of wood on 7.1 vs higher quality of way lower amount of wood on stereo. You get a product in another quality bracket.
And then you need to count in the receiver/amplifier. Their cost is high and their power usage is not minuscule.
If you're talking Atmos effects only, those can be done by DSP, there's an application from Dolby for that.
For native recording, if the band is compatible why not, Pink Floyd used quadraphonics and panning to get surround even in 70s, but Maiden have been always live mixed in stereo so why even bother. Of course I wouldn't mind if there was native surround downmix published, that would mean we could rip out some instrument stems out of it.
