The 'bit' type has no relation with this problem.

In languages as Java and Pascal boolean values and integer values are two very
distinct types. In languages like C/C++/D/Python boolean is a kind of subset of
integer type. This means 

int x;
bool b;
x = b; // OK, it's a subset
b = x; // error, generally

There are many situations where the implicit true -> 1 conversion is handy.

D accepts the implicit true -> 1 conversion in all cases. Refusing it only in
BigInt assignements breaks the language simmetry. I don't think the implicit
true -> 1 conversion will be removed from D2, so I think it should be present
in BigInts too.
