It isn't. It can add just some seconds (probably less than 5 on fast SSDs, even less if you don't have too much RAM). If people can't wait this little they need to have their lives / jobs / mental health fixed rather than add more orders of complexity (with according increase in problems) into the computers.
On my work laptop (modern HP Elitebook), sleep doesn't work at all (laptop just turns on again after going to sleep), so I'm using hibernate exclusively. Waking up from hibernate takes longer than one minute.
On the other hand, my private laptop (Huawei Matebook) wakes up from sleep in less than 10 seconds.
On my MateBook 13 (2020) the Fn and Shift Lock lights are turned on, while the laptop is still powerd on, but not under OS control anymore:
Sleep takes 6 seconds down and 2 seconds up.
Hibernation is 9 seconds down and 20isch seconds up.
Shutdown is 20isch down and Boot is 22isch to desktop (fastboot=off).
