Now I think we shouldn't deprecate and remove wantobjects=False. Tkinter was partially broken with wantobjects=False, on other hand, it was partially broken with wantobjects=True. Many bugs was fixed last months, all tests now work with wantobjects=False, and I hope Tkinter now correctly supports both mode.

Besides using in old third-party code, this parameter is very helpful for testing. Tcl/Tk changes internal details from release to release, so when in one release Tk function returns list or integer, in other release it can return special object ('dict' or 'pixel'). Tkinter should be more stable against changing of return type, and wantobjects=False helps in detecting some such cases.

I propose to close this issue as fixed.
