Both these are good observations and I'll act on them.

I've not read of the FTP before; I welcome it, and take on board that it
improves privacy by keeping a script offline. My first thought is that doesn't
affect the suggested BIP, so my next update here won't include it. I recognise
it would improve mainnet use of scripts though, so do expect to return to it.
