notes/python_concepts/import_traps: Attempt to cross-reference bugs.python.org tickets?

[pfalcon]

https://github.com/ncoghlan/misc/blob/master/notes/python_concepts/import_traps.rst is insightful. It's hard to believe that at least some of the issues there was not reported at https://bugs.python.org/ . Was there an idea to try xref any such bug ticket, to provide more in-depth coverage of the matters?
