I think you can extend this argument to just about any piece of software on 
the system..

That is a pretty major inconvenience. It's like saying "Oh well if you want to 
use NSS you should rebuild things" - you can do it but it's very 

There is always a trade off but it seems most people don't think Heimdal is 
insecure enough to disable by default. (Has it has any bugs that have been 
exploitable in an unused configuration recently? I don't believe so).

Personally I'd be more worried about the PAM code.
