If the generated code are same, and it's in the std library, which means no
difference in the backend.

Then I'd rather write:

struct A
{
        bool flag1:  1;
        bool flag2:  1;
        // uint "",  6;   // this should be auto-magically generated by the compiler
}

(the code is more clear, and the compiler can give better message).

than this:

struct A
{
    mixin(bitfields!(
        bool, "flag1",    1,
        bool, "flag2",    1,
        uint, "",         6));
}
