Just thought I'd throw this out there (was think of making an addon) and see if this belongs here:
A component, something like:
{{#state-group 'stateName' identifier=model as |state|}}
<!-- use state here -->
{{/state-group}}
<!-- or buffered -->
{{#state-group 'stateName' identifier=model buffered=true
onapply=(route-action 'saved')
as |state actions|}}
<!-- use state here -->
<button onclick={{action actions.apply}}>Save</button>
<button onclick={{action actions.reset}}>Reset</button>
{{/state-group}}Basically every time this renders you would have like a persistent state object that can be modified without having to inject or make a CP.
