 Review comment:
   Personally, I'd prefer to be the templates more neutral. They may have 
`--job-id-seed` by default, provided that it's not mutually exclusive with 
`--job-id` option. So if both options are present, the system would pick the 
`--job-id` by priority (as it was originally described in the ticket). But that 
just my own preference.
