It’s a completely viable solution for certain situations, say, having a .button class. The things mentioned in that twitter thread have nothing to do with that.
I was commenting on "As soon as you have recurring product prices, you’re encouraged to use @apply to group those classes. ". It's certainly technically possible to create a CSS class. But AFAIK the recommendation is loudly and clearly to use components https://tailwindcss.com/docs/reusing-styles#extracting-compo..., and for good reason.
I follow, but even that part of the docs acknowledges the use cases solved by @apply. No denying it’s a powerful gun to shoot your foot with, but it has its merits. Especially in the OPs context of some bespoke e-commerce CMS, which might not even have a frontend pipeline more sophisticated than grunt or something.
