Maybe not.

Stubs were not included in the core until 8.1.x and 8.2.x. So your situation
is normal. But if you follow the TEA guidelines and stubify tkinter, you
should not have any problems when upgrading to a new version. I know for a
fact that this worked for me when I upgraded from wish 8.1.x to 8.2.x: I
didn't need to recompile the Img extension, which was properly stubified.
