Well, I can't help with "requiring".

But once the logical abstraction is established, the 1wire library needs
to fit into the concrete code that maintains the abstraction in a way
that won't require it [more than absolutely necessary] to pay attention
to 1wire-specific issues like co-ordinating scanning /alert or writing
to /simultaneous, and which won't break [more than unavoidably] when
Things Happen to the bus.

And that in turn requires more support from the 1wire library than the
ability to call read, write, and getdir. That's the easy part.
