We did send some e-mails on boot-arch ML in the past [1]. The subject is quite
controversial since there are a lot of opinions on this.
I think Linaro is working on a device tree evolution project at the moment with
one of the subjects being device tree verification.
We can certainly discuss more during Linaro Connect.
