> To make a potentially viable concrete proposal here, I think a reasonable first step would be to change the ".pth" file processing code in site.py to emit PendingDeprecationWarning for the 'if line.startswith(("import ", "import\t")):' branch. PendingDeprecationWarning because you don’t think we can remove this functionality in 3.9? > In addition to helping to determine the scope of the compatibility break being discussed here, such a warning would also be usable as a debugging tool. > > I'd also suggest updating "python -m site" to list any pth files that it finds, and categorise them as simple sys.path additions (which are generally fine), and arbitrary code (which can be problematic). Great idea, +1
