The charge pump can be pulled low, and then pumped back up, but yes, failure modes and power cycling behaviour is very important. >> Also, if there is any type of feedback line, you could try putting a >> pressure regulator in line, or maybe a delay circuit/relay in the >> path.

Basically you pointed out a couple of shortcommings on the UI design, and suggestions on layout. Might make the beginnings of a nice section in the docs, on recommended layout rational. Best of luck!
