Rounded corners really were all the rage for a while and we needed support for it! I remember in the early days cobbling together elements with top-left, top-right, etc image slices. Want't really too long ago.. maybe 10 years?

To me this is core ajax and php era, so ~2002-2006 which would be about 18 years ago.
By the time CSS standards for rounding corners arrived a lot of pain has been inflicted on us developers, but by now it feels as if this era never existed (same with pre/post flex to take another CSS milestone)
Firefox had it from 2006, prefixed.
IE was the holdout, not having it until v9 in 2011.
