Hi Dmitry,

How do path templates compare to key origin identification[1] in
output script descriptors?

Could you maybe give a specfic example of how path templates might be
used?  Are they for backups?  Multisig wallet coordination?  Managing
data between software transaction construction and hardware device
signing?

Thanks,

-Dave
