tl;dr;

It is dangerous to expect that o= ther seed than "xprv" does not contain bitcoins or that "xpr= v" contains only bitcoins, because technically are both situations pos= sible. It is still safer to do the lookup; the magic itself is ambiguous.

Serial= ization magic of bip32 seed is in my opinion completely unnecessary. Most o= f software does not care about it anyway; You can use xprv/xpub pair for ma= in net, testnet, litecoin, dogecoin, whatevercoin.

Instead using the same seed (xprv) and then separate th= e chains *inside* the bip32 path seems more useful to me.
