It has some interesting properties though. I recently revived a Forth I wrote in 1988 to bring it up to full ANSI compliance and it was a lot of work. It also gave me a renewed respect for the incredibly small footprint that can get you a working forth environment. Originally the program was ~900 lines, and it probably could have been shrunk quite a bit further. But there are a lot of not-so-elegant parts of the standard that caused some bloat.
