Not sure. It matches semantically better.
And you get correct coercion too. With
_Bool value = 2;
the value becomes 1, i.e. true, while
unsigned int bit:1 = 2;
stores 0, i.e. false, because of wrapping.
Of course problem is storage size. _Bool usually occupies one word due to
performance reasons. You would still have to write
to get packed bit-field to spare memory.
On the other hand, integer bit-field allows to preserve API by enlarging the
size if it turns out that the value should be able to represent more than
two different states.
