When I first learned about Tailwind I though "wow this is amazing!", but it quickly became obvious I was more or less learning another "language", which I really didn't need when re-entering the crazy world of frontend. I might reconsider it again once I am more comfortable with what frontend has become, but that is still quite a bit away.
A big part of Tailwind's value is that it provides a curated, well-documented subset of the most important CSS attributes. The utility classes are consistently and concisely named (unlike many native CSS properties, which grew organically).
You're totally right that it is yet another abstraction, and that can be tiring. Personally I found it to be well-designed and transparent enough to make it worthwhile.
