Especially when multiple chains are combined (multisig) for P2SH usage, defining things like a gap limit becomes impossible without knowing some metadata. However, perhaps it is possible to define something like "BIP44 import-compatible", meaning that the application doesn't actually support all of BIP44 features, but does guarantee not losing any funds when imported? Similar things could be done for other purpose types. -- Pieter
