Using Tailwind does probably establish a floor on the difficulty of quickly diving into a new project (assuming the Tailwind config hasn't been customized too much). That might be great if you're in the position to force your team to switch from unstructured/undisciplined CSS to Tailwind, but not in a position to force your team to use some even more structured approach that supports even better consistency and composability (like a set of components). Granted, Tailwind is probably intended to be used to create a set of components, although a lot of their official messaging (like Tailwind UI) seems to actively work against that approach.
