Kaimartin,

Counterpoints:
* Parametric footprints can be saved. This feature compliments your
standard library, not detracts from it.
* Parametric footprints makes PCB more accessible. For new users the
process of creating one's own footprints can be quite daunting.
* Great potential to reduce library clutter, duplication, and maintenance.

This makes generating footprints for custom connectors (ie. common 0.156in
headers) painless and more or less instant. That sort of flexibility is
downright useful regardless of how it was implemented.


- Aside 1: believe it or not we get new users every day, it just that when
they see the tools, they tend to run away...


- Aside 2: It seems like everyone who actually needs to use PCB on a daily
basis has their own custom fork. Igor2 has been kind enough to share his
flavor of PCB, be kind to him.
