Nothing prevents you from doing that. The infrastructure is
there. Just write a (threaded ?) match provider. Also, even if
we fetch the entire list beforehand it doesn't make sense at
all to fill a fixed list provider with 40000 items.

The "start fetching after reaching a minimal fragment length"
part is already in there. No need to extend the FixedList
provider, however. Just write your own.
