Has 5.x *really* gone that far downhill? :(

I've been doing the above since about day one ... *but* ... is this the 
case if you set WRKDIRPREFIX= to somewhere else in /etc/make.conf?  I 
don't build the actual port *in* /usr/ports, so the only thing that gets 
written in /usr/ports is /usr/ports/distfiles ...
