Yes, but more in a QoL way. I say negative as in - if you don't have it you lose a customer, rather than if you have it, you gain a customer.
If performance is a feature, then it's not an important feature. Otherwise, people would use Paint, for everything.
Or put it another way, you want to do X1 task. It's editing a picture to remove some blemishes from skin. You could use a console, to edit individuals pixels, but it would take months/year to finish the task if you are making changes blindly, then checking. It could take several days if you are doing it with Paint. Or you could do it with Photoshop in a few minutes. What difference does a few ms make if you lose hours?
Now this is only task X1 which is edit blemishes, now you do this for every conceivable task and do an average. What percent of that task are ms loses?

I completely agree with that take. That's exactly the reason why, for example, whenever I'm about to do some "Real Work" with my computer (read: heavyweight stuff), all Electron apps are the first to go away.
My work uses Slack for communications, and it is fine sitting there for the most part, but I close it when doing some demanding tasks because it takes an unreasonable amount of resources for what it is, a glorified chat client.
