A bit of delta but is there any chance we can either deprecate
.use_hierarhcy or at least make it global toggle instead of subtree
thing?
So what you are proposing is to have all subtrees of the root either
hierarchical or not, right?
This seems needlessly complicated. :(
Toggle wouldn't help much I am afraid. We would still have to
distinguish (non)hierarchical cases. And I am not sure we can make
everything hierarchical easily.
Most users (from my experience) ignored use_hierarchy for some reasons
and the end results might be really unexpected for them if they used
deeper subtrees (which might be needed due to combination with other
controller(s)).
Do we have any idea about who those users are, and how is their setup
commonly done?
We can propose work arounds here, but not without first knowing work
arounds to what =p
One thing that would really influence this, for instance, is whether or
not they limit at all levels in the tree, etc.
