   Another possible API:

   const cli = createCli({
     router,
     modify: modifier => {
       modifier(router.deeply.nested.fooProcedure, command => {
         command.addHelpText(`be careful with this, it's destructive`)
       })
       modifier(router.some.other.barProcedure, command => {
         const abcOption = command.options.find(o => o.flags.includes('--abc')
         abcOption?.hideHelp()
       })
     }
   })
   
   cli.run()

   or something like that

   devil's advocate to myself, here's how you'd do that today:

   const cli = createCli({router})
   const program = cli.buildProgram() as import('commander').Command
   
   const findSubcommand = (...path: string[]) => {
     let command = program as typeof program | undefined
     for (const p of path) command = command?.commands.find(c => c.name === p)
     if (!command) throw new Error(`command at path ${path.join('.')} not found`)
     return command
   }
   
   findSubcommand('deeply', 'nested', 'foo-procedure').addHelpText(`be careful with this, it's destructive`)
   findSubcommand('some', 'other', 'bar-procedure').options.find(o => o.flags.includes('--abc')?.hideHelp()
   
   cli.run({}, program)

   which is really not so bad, not all that much more verbose and more obvious what it's doing. but not type safe
