Actually, contrary to to what you'd intuitively expect, that method
does *not* ignore receive routes. Only DNS servers are ignored. The
only difference compared to the «Automatic» is ignore-auto-dns=true
gets set.

This is a very good example of what was getting at. Instead of having a
separate "method" just to ignore received DNS server, this should have
been a simple checkbox to override the default behaviour, in the same
way privacy extensions already are.

With the current arrangement, if you want to allow the user to ignore
routes but not DNS servers, you'd need a third «Automatic (..)»
flavour. If you want to allow to ignore both routes *and* DNS servers,
you'll need a fourth. One "method" for each possible permutation of the
settings simply won't scale.

That would be one possible use case. Note that I'm not really talking
about a specific need of my own here, but rather to make it more
flexible in general than it currently is.
