As contributor i hereby state that i support the change:

The proposed change would allow to better decouple further evolution of EST without
BRSKI (not having to bothre about what BRSKI added when you do not use it), and vice versa.
For example Registrar/MASA being a pure BRSKI/Voucher channel would not be impacted by
EST legacy anymore.

The change could also help to simplify implementations, although it not clear to
me how big the simplifications would be. To the best of my (limited) implementation
experience, if EST and BRSKi where to be implemented separately, the URL routing
to those two implementations could be simpler, by routing all /.well-known/est 
URLs to BRSKI instead of having to enumerate the BRSKI URLs under /.well-known/est
explicitly.

To the best of my understanding, BRSKI implementations so far are still experimental,
so this change would not have a relevant negative impact on products.

I therefore can see no technical downside.

Thanks
    Toerless
