ModelFormSet allows the initial={} parameter, but InlineModelFormSet doesn't; simply because it's missing kwargs. Patch attached.

I just ran into this today. I expected to be able to pass initial values into a BaseInlineFormSet that I got from an inlineformset_factory. It is useful for setting default values on unbound forms.
Also similar to #12213

I attached a starting point for supporting initial values for model formsets. If this approach and implementation is accepted, I might then work on tests and maybe adding an example to the doc.

This second patch is more elaborate, as it includes tests and also adds support for inline model formsets (taken from initial patch).

I added ticket #17927, that is request for the same functionality for BaseGenericInlineFormSet
Sorry, broken patch. Using initial on ModelFormSet overrides queryset populated values.
If anyone else is interested in adding initial= support for *ModelFormSets, I'll happily patch. I'd expect the initial values to populate the extra (empty) forms only. If it's a single dictionary, repeat it on all extra forms; if it's multiple then apply in order.
