Config/plugin/readme files for Emacs and Vim in Misc have been deleted. The only remaining ones are for Wing IDE. Here is a patch to remove these files.

What is the advantage to deleting the Wing IDE project files, other than making it harder to use Wing to work on Python?

Closing as this seems abandoned. Feel free to reopen if not.

Since the files have effectively been abandoned, I think removing them should be considered now.  The three files in /Misc, for wing-3, 4, and 5, are
python-wing3.wpr
python-wing4.wpr
python-wing5.wpr

The current version of Wing is 8.1.1.  The files were last edited in March 2011, a decade ago, by M. Foord.  The last contains

                                     u'Lib/unittest/test/__pycache__',
                                     u'Lib/__pycache__',
                                     u'build',
                                     u'Doc/build'],

*4.* is the same except for the version comment.  Both are specialized for working with Lib/unittest, failing to exclude most of the other __pycache__ directories.  I wonder whether current Wing now knows that it should ignore __cache__ directories.  (I considered emailing support@wingware.com, but decided to wait.)  In the absence of more comments, we could inquire on python-dev.

In 2019, these .ini-format configuration data files were marked as executable scripts.  I believe that this was a mistake.

IMO it's ok to remove these files. If WING is maintained again, it will be trivial to add again these configuratin files. I suggest to only remove these files in Python 3.11.
