It comes down to your use case.
You may find that writing custom types/providers is easier than using
Augeas (it certainly is for me in general).
Also, remember that editing LOTS of files creates LOTS of resources and
relationships which means a longer compile time (fewer nodes able to be
managed) and longer runs/more resources used on your clients.
I prefer to keep things as efficient as possible and only edit parts of
files when I have requirements from other users to do so. Otherwise, you
could end up with (quite literally) tens of thousands of resources and
relationships. Then you'll be back asking why everything is so slow ;-).
