Sorry, no - this'll break most css-based layouts.
I've tested it with the included "vertically-aligned" css file, and that breaks.

In fact, I have vague memories that one of the reasons I didn't go
with this was because of the difficulties of getting css to work
consistently with it.

In the "best practices" section of the docs, I recommend having global
settings in an external config file, and including that in every form.
If you set this, you'll get the same effect:

    id: form
    auto_id: %f_%n
    default_args:
      elements:
        Radiogroup:
          auto_id: $f_%n_%c
        Checkboxgroup:
          auto_id: %f_%n_%c

I'm also actively working on automatically generating JavaScript for
filters + constraints - and to use that, you'll need `auto_id` set
anyway.
