This allows the removal of its O(n) .get_field_by_name method and many

While fields were initially stored in a list to preserve the initial
model definiton field ordering the auto-detector doesn't take field
ordering into account and no operations exists to reorder fields of a
model.
This makes the preservation of the field ordering completely superflous
because field reorganization after the creation of the model state
wouldn't be taken into account.

ModuleNotFoundError was introduced in Python 3.6. It is a subclass of

is not raised for other errors that can occur during an import. This
exception instance has the property "name" which holds the name of
module that failed to import.

function signature can't be used by mistake when upgrading Django. When
the new argument is True, the sequences of the truncated tables will
reset. Using a single boolean value, rather than a list, allows making a
binary yes/no choice as to whether to reset all sequences rather than a
working on a completely different set.
