Only historical coincidence, I think. I "tkwidgeted" everything in sight in May 2000, Brian added ttk widgets in March 2008, and I added some more stuff in August 2015. So

(a) ordinary Tk widgets introduced later than 2000 haven't really been considered.

(b) ttkspinbox was included in the August 2015 update; I may have assumed that Tk would be updated to 8.6+ for 3.3.0 on all platforms, but this slipped through the cracks in the compiler toolchain update.
