Bech32-P2WSH BIP32 derivation path I know that the deriving path for Bech32 is 84, but what about P2WSH addresses path is it the same?

I've been reading https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki but nothing on there. 

For example, I'm using path 84 to derive P2WSH addresses, but electrum uses that path to derive P2WPKH addresses. I would like to know the correct path that I should use, so my mnemonic phrase becomes compatible with other platforms. Something like 44 and 49 paths.
P2WSH addresses have no deriving path since a P2WSH output does not send to a public key and P2WSH encodes a script, not a single public key.

Thanks to @Pieter Wuille for clearing up things.
