The only stage that freeze the RF licensing commitments is when a spec
reaches Recommendation (which to me at least is a good motivation to get
small set to Rec early rather than to wait to a full spec many years
later).

The impact of other stages on the patent policy are as follow:
* each Last Call starts a new call for exclusion, under which any
feature that wasn't available in the previous last call can be excluded
by a WG participant
* you can only go to Proposed Recommendation if there is no open call
for exclusion (which means there needs to be at least 60 days between
the last last call and moving to Proposed Recommendation)
* the minimal time between a first public working draft and a proposed
recommendation is 150 days (due to the first window required for the
first call for exclusions)

My separate perspective on the "long time to go through the
Recommendation track" is that the time needs grows non-linearly with the
size of the spec (due to the rule that to go out of Candidate
Recommendation, you need to create test cases and show interoperability
for each feature — and creating test cases and showing interoperability
becomes harder as you add new edge-cases features).

Also, WebIDL/JavaScript are sufficiently flexible that in many cases,
you can reasonably easily create modules (e.g. partial interfaces,
partial dictionaries) which allow to complete a particular aspect of a
spec.
