 In https://github.com/django/django/pull/12750 and
 https://code.djangoproject.com/ticket/30372 we stopped watching the
 translation files that Django ships, to improve the performance of the

 I believe we can go a step further and stop monitoring all third-party
 packages for changes by using the sysconfig module:
 https://docs.python.org/3/library/sysconfig.html. With this we can get a
 list of different Python system directories, for example:

         data = "/Users/tom/PycharmProjects/github/orf/django/venv"
         include =
         platinclude =
         platlib =
         platstdlib =
         purelib =
         scripts = "/Users/tom/PycharmProjects/github/orf/django/venv/bin"
         stdlib =

 We could simply not watch any path under the `purelib` directory to start.
 This would exclude a huge number of files from being watched - Django
 alone has 824 individual files that would be excluded, and it's safe to
 assume that a large project with many third party dependencies would have
 several thousand.

 This would be a breaking change - personally I sometimes find myself
 navigating into third party code and making small changes while debugging,
 and I'm sure others do this from time to time. However I don't think it's
 a common occurance for most developers and I'm not sure everyone paying a
 cost is worth the benefit to a small number of people.
