I should explain this better. Having a default is wrong because:

1. as mentioned, it can be overlooked in the porting process

2. if the default doesn't work right for some system, the temptation will be to 
'fix' the default in ways that are untested (and therefore broken) on other 
systems. Working on one system's code should not affect other systems!

3. it leaves unknown to the reader what systems that may apply to

I know the powerful temptation to avoid copypasta. But I have decades of trying 
it that way, and it just leads to lots of time wasted tracking down bugs. This 
includes historical bugs from doing it that way with druntime & phobos.
