> {{GenericCli}}-based commands have a {{\-\-verbose}} flag, which has two effects:
> # some subcommands print additional details
> # stack trace is shown in case of exception
> I think (1) is more generally useful, while (2) is geared towards developers.  To avoid making {{--verbose}} commands overwhelming for users in case of errors, I propose to split these two effects.
> Possible solutions:
> # multi-level {{--verbose}} mode (allow specifying {{-v}} more than once to get more details)
> # introduce a new flag to enable the stack trace
> # only print the stack trace if exception message is not meaningful (eg. empty or {{"null"}})
