FUD surrounding these packages mostly around resolving a kicad issue suspected to be caused by an incompatibility between wxWidgets 3.1.2 and wxPython 4.0.7

0. except for wxmac, none of these have a listed maintainer
1. wxPython releases depend on non-release wxWidgets revision
   With help from their forum, i got wxPython 4.1.0 building
   The result however is not usable probably due to it being in a buildPythonPackage
   1.1 issues due to the mismatch between wxPython's bundled wxWidgets and nixpkgs' wxGTK persist (wxPython: 4.1.0 -> 4.1.1 #135607)
   1.2 upstream issue about this: Update to wxWidgets 3.1.5 wxWidgets/Phoenix#1961
2. we now have wxGTK3*-gtk[2|3] (wxGTK3: make gtk2 and gtk3 specific variants #90428)
   While a practical and well meant approach by @peterhoeg to transitioning to gtk3 (wxGTK: use GTK 3 by default #73145)
   This means we have 4 packages providing wxWidgets,
   plus wxmac and possibly the need for a wxPython.wxWidgets
3. wxPython, wxPython30, wxPython_4_0
   What attribute should wxPython-4.1.0 be?
   @veprbl seemingly suggested the _4_0 here
4. pkgs.wxGTK provides wxGTK but the pname is wxwidgets, their docs suggest it should be wxGTK?
   4.1. wxmac should be wxOSX?

possibly interested parties
