Comment:
I wonder if we could introduce a new filterspec API that relies on
[https://github.com/django/django/search?utf8=%E2%9C%93&q=sticky the
''sticky filter'' behavior] of the ORM for this purpose instead:
{{{#!python
list_filters = [
('multi__value', StickyFilter([
'lookup',
('other', SomeFilterSpect()),
]))
]
}}}
The `StickyFilter` (or whatever name we find for this object) would
delegate filtering and rendering to its underlying filters but make sure
to mark the `queryset` object passed to it as having ''sticky'' filters
(aliases are reused when a queryset is sticky) before calling each of its
filters `queryset(request, sticky_queryset)` methods.
