plone.app.contenttypes, plone.app.event and plone.app.widgets

Hi,

we have currently a state of confusion referring to 
plone.app.contenttypes, plone.app.event and plone.app.widgets.

all those packages gets heavily pushed forward to Plone 5 at the moment, 
which is a good thing. But in my opinion a real world useable version of 
Plone 5 is realistically expectable somewhen at the end of this year. 
Thus in real project life we're going to have to stick to Plone 4 a 
little longer.

So, to speak for myself, when realizing projects, with future migration 
paths in mind, i use plone.app.contenttypes and plone.app.event and 
Plone 4.3 latest, and skip plone.app.widgets, since they make too much 
troubles in Plone 4.

I cannot find an official documentation which versions are supposed to 
be used in which version of Plone and what a user can expect this 
packages directing in future.

I also asked Hannes, but he's also unclear about this questions.

May someone enlighten the Community please? ;)

Cheers Robert
