On Registries

Since it seems like this issue won't die, it's at least fruitful to discuss.

For the proponents of registries, can you please describe what difference,
if any, there is for the web development community and user agent authors
between

window.crypto.subtle.encrypt("AES-GCM", foo, bar)
and
window.crypto.subtle.aes_gcm.encrypt(foo, bar)

I assert that there fundamentally is none. Both, once implemented, are
parts of the Web Platform. Like any other feature in the Web Platform, we
want to see such work develop through consensus. Like any other feature of
the Web Platform, it is extremely unlikely for two groups, let alone three
or more, to develop competing definitions. The only historical precedents
for this has been WHATWG vs W3C, or UA Vendor vs (WHATWG || W3C), and both
are recognized as unfortunate failings, not desirable/normal outcomes.

Let's stick solely to discussing how things work in the W3C and the Web.
What IETF does, while important, is not the same as what the W3C does - and
that's OK.
