As always, it's useful to specifically identify what challenges this
presents, to better inform the debate. Given that CAs routinely say "it's a
short implementation timeline" - and this is six months for an existing,
well-supported part of the WebPKI (as opposed to new features, such as
improved validation methods, CT, or CAA) - and browsers are routinely used
to shipping things on the order of O(days) - having concrete, actionable
data helps ensure forward progress is made.

To reiterate: This is flexibility as to what the Baseline Requirements
require, with the acknowledgement that absent concrete data, it may be
appropriate and necessary to go above and beyond what the Baseline
Requirements require to ensure specific security needs are met. This is
similar to, for example, requiring the use of Certificate Transparency to
ensure an EV certificate is recognized as such in some browsers.
