I suggest that above some default number of items, a !ModelChoiceField
should automatically switch to raw_id_fields mode. There could be a new
parameter to change or remove the limit.
I've seen a couple of instances lately where a new Django admin page
mysteriously would not load, with CPU pegged, and it turned out the model
being admin'ed had a !ForeignKey to a table with millions of entries,
which turned into a !ModelChoiceField in the admin that tried to build a
widget with millions of items... it didn't work very well. This was the
default behavior, not a result of deliberately choosing to create a
ModelChoiceField on that big table.
