Since RTCs aren't _actually_ essential for Linux kernel operation,
the former clearly applies.

Other people may have differing opinions, but having worked with a
large number of SoC platforms where the RTC is reset when the SoC
is reset, or even platforms where there is no RTC at all, it brings
a different perspective to this that people who have only ever
experienced systems where the RTC is always true do not have.
