Sure, but that's what conference calls are for.

Most big tech companies automatically start a call for every large scale incident, and adjacent teams are expected to have a representative call in and contribute to identifying/remediating the issue.

None of the people with physical access are individually responsible, and they should have a deep bench of advice and context to draw from.

It shouldn't be too stressful. Well-managed companies blame processes rather than people, and have systems set up to communicate rapidly when large-scale events occur.

It can be sort of exciting, but it's not like there is one person typing at a keyboard with a hundred managers breathing down their neck. These resolutions are collaborative, shared efforts.

These sorts of low-power coprocessors are quite common. You can buy Cortex-A/Cortex-M combos from multiple manufacturers on digikey.

It's not just big application processors that have them, either; some microcontrollers like the ESP32 have them as well.
