I saw no discussion or resistance to the idea of that folder being created for the user. In fact I saw Roman asking something this:

I believe yet all have agreed to ~/.local/lib/pd/extra as the default
install path (and most recent Deken uses it).

There was some concerns about creating directories without asking. Now,
do those concerns still apply with above default install path? It seems
pretty normal that applications do stuff there. Is anyone still against
auto-creating? 

Roman

it seems indeed that the main obstacle for automatic directory creation
has gone with this new default user-specific search path.
if there is some consensus, i will happily re-enable the directory creation.
(but it seems that everybody has gone into sleep mode again, and will
only awake after the next release)
