Hallo!
as far as i have understood it, the standard library wants to duplicate externals: e.g. an object that allows interfacing with the serial port would be a copy of iem/comport that is named hardware/comport (or whatever). thus it would not rely on "3rd party" externals, but on stdlib "internal" libraries. (with duplicate code and everything that follows from it)
As far as I undestood it the code of e.g. comport would go in this standard lib (e.g. to hardware/comport) but should not duplicate the code - instead the iem/comport code should be obsolete and now maintained in hardware/comport.
But as the others convinced me at the pd conv I don't think that this will happen soon (and "soon" in pd time means maybe 8-10 years ... ;)
