In a way it is a Tcl thing. The earliest Tcl including the original Tk 
did everything with strings using implicit conversion as needed. So in 
Tcl W and 'W' were treated as the same thing, no need for a constant.
When Tkinter was invented Python needed constants or strings so Tkinter
provided for both.

Personally, I generally use the strings for options.
