Not only repeated modifications. It simply should not do that in any 
case, without asking back!

> Using /etc/paths to add the MacPorts paths is not recommended because that appends the MacPorts paths to the default, while we want the MacPorts paths to be prepended. We want MacPorts versions of software to supersede probably older versions provided by the OS, not vice versa as using /etc/paths will do.

It depends on the order in your /etc/paths. If I put it first, it is 
first. The advantage of /etc/paths is it is applied even to the 
graphical environment, not just when running a login shell.

It did not, never.

People using MacPorts are those who know about the insides of their 
system and want to customize it. I think they should at least be able to 
read and follow documentation.
