Exactly. It works today, because:

- the device nodes are there.

Ergo: udev should create the device nodes

- the kernel autopartitions the device on any open (both main device and
the subpartitions) when it notices a changed media. No polling
required.

Ergo: the kernel should continue to do this.

We should _not_ be in the situation where either of these things aren't
true.
