MarsSeed [1] filed a deletion request for python2-flask [2]: This legacy Python2 version of the Flask web application framework is not needed or useful to keep. For production purposes it is not just deprecated but also insecure. Current AUR consumer python2-flask-table is already broken due to missing another dependency. And python2-requests only optdepends on it, but actually this was originally a checkdepend of that. However, I found out last year that executing the test suite of that package would have required recreating an excessively large and complex dependency chain just for the purpose of testing that one build. Therefore I decided to put python2-requests' checkdepends in its optdepends, and make the test execution inside check() get launched only if all of the optionally defined checkdepends are satisfied. As several of python2-requests' optional checkdepends don't exist on AUR, no check() function gets run by its PKGBUILD. So at this point, the current maintainer of python2-requests would do best to remove those optdepends, as they are superfluous. Safe to drop this package; no negative impact.
