[New-bugs-announce] [issue32825] warn user of creation of multiple Tk instances

[mps]

New submission from mps <wiztricks at gmail.com>:

tkinter is the first GUI interface used by novices. 
They often get in trouble when they create a new Tk instance instead of a Toplevel.
It would be helpful to output a warning message in this case (i.e. checking _default_root is not None and _support_default_root is True in the Tk initialization).
Thank for your attention and best regards.

- mps.
