Sleight. Just because I used to make the same mistake myself. ;)

Speaking of Dexterity:

Sleight, meaning dexterity or deceptiveness, comes from the Old Norse  
slœgð.[3] Sleight of hand is often mistakenly written as slight of hand.  
Slight descends from the Old Norse slettr, meaning plain, flat, even,  
smooth, level.


Sorry for the aside, I found it amusing and somewhat relevant, with the  
Old Norse (Martin ;) behind Dexterity, etc. :)

Yup, the idea is to make AT *optional* (but still default), and to be able  
to supply a Dexterity-based alternative. Then we can work on the migration  
story from AT->Dexterity without that being a blocker for 4.0.

In other words, if you start a new project, you'll probably want to look  
into Dexterity-based types — if you have an existing site running  
Archetypes, you'll probably want to keep that for the time being. This  
means that developers that know what they are doing and/or new users could  
go with Dexterity immediately, whereas the people that mostly care about  
keeping their existing site running could stick with AT.

We might also choose to only support the new layout model with the new  
types, if this makes it easier to manage. We'll cross that bridge when we  
get there.

This would have to be named Plone 5.0. Replacing the default types  
approach is a huge undertaking, especially from the upgrade side. If Plone  
5.0 was a release that only did this change, I'd still be happy with it. :)
