Mk/Uses/alias.mk was an attempt for compat with DPorts, but has rotted. This feature was never documented in the PHB, so there is no work to be done by the docs@ team. Nothing against DragonFly, but if DPorts still needs FreeBSD 9 support, they really should work that out with upstream projects. Ultimately, we don't need to keep carrying this outdated feature that doesn't affect us.
