Yes, that's the reason why we remove it. It was legacy stuff from 1.1/1.2 and
with 2.2 it is the right time to do a cleanup in the codebase.

It is a bug. We should not use UINamingContainer.getSeparatorChar(...) to
render that hidden field and enforce ':' instead. The reason is the intention
of use javax.faces.SEPARATOR_CHAR is to avoid the collision with css
when you use the ':', but in this case the intention is to create a hidden
field, with no real underlying component, so it is better to let ':' on the js
file. Please create an issue in MyFaces issue tracker and I'll fix it on all
affected branches.
