Why do still have to *reboot into* Verbose mode?

I'm still completely green with Linux but you gurs really know what you're talking about.

As it happens, I've been using Apple products since 1979, loved the Mac, was depressed by those clunky Gates/Jobs Windows Wars in the nineties, loved OSX still more, mistrusted iOS and recent attempts to restyle Mac GUI to behave like a widescreen iPhone, and have tended to doubt what OS11 will bring to our lives that Lion didn't pretty much give nearly twenty years ago.

But I have never learned Linux beyond slavishly typing out suggested command lines from these threads in order to summon its arcane magic (in the manner of a cargo-cult).

Perhaps you wise people can answer a question that's been puzzling me for years:

When any Mac hangs during its Apple startup screen, why is it that you then have to reboot and hold down a key combination in order to get see what's going wrong "under the hood?" When my car engine begins to shake, I have the option to pull over, leave the engine running and look under the bonnet (I'm British) to see which parts are moving erratically.

Why has no one made it possible, during startup, simply to hold down a "V" key, or something, and have the apple/thermometer graphic replaced with a real-time Terminal list of commands as they are executed and feedback generated?

By now, after twenty years of investigating problems, I might have saved a good week's worth of diagnostic time wasted on hard shut-downs and Cmd-V reboots. Would it really be rocket science to have a quick-key that just lifts the Apple hood so you can see what's happening real time?

Why would that simple convenience seem to be rocket science to implement?

Thanks for your thoughts,

Eric
