One question and one suggestion. Responses -- from the Team, not  
necessarily from Hanno -- need not be 'at this point', January some  
time will be fine.

 From my viewpoint of click testing (and extending then click testing)  
such TPs will be warmly welcomed.

- "include it"

+ "include the change"

====================================================
Removal of a feature/code from a technology preview,
removal of a feature/code from a Plone core release,
trust in developers
====================================================

Recalling from the Evangelism forum a post <http://n2.nabble.com/Should-we-be-doing-things-like-this--tp1587801p1602360.html

* remove from the base during technology preview phase?

* remove from the base following a release?

(I understand that such removals are exceptionally rare, and always  
well-justified, but newcomers encountering the phrase may be alarmed.)

In clarifying the phrase above we can express both:

* the rarity and timeliness of such removals

and more importantly

* the underlying fact that trust is very well-placed.
