The idea here was to keep longer schedules more manageable. And during
testing I found it more ergonomic to have a file.

It also has the advantage that the file can be reused by other tools,
dump-classifier (awful name, I admit), included in that github gist, is
one example, it uses the schedule (and some more information) to
calculate which packets would fall outside their "windows" in a pcap
dump.

Anyway, if there are use cases that having the schedule in the command
line helps, I would be happy to add it.

Cheers,
