I think it will break the booting of MIPS/RISCV QEMU virtual machines,
because RTC is an necessary device.

For the maintenance, I don't know whether Goldfish RTC depends on the
code under drivers/platform/goldfish. If not, I think I can maintain
it (I think other parts of Goldfish will be removed, I'm able to
maintain RTC but I'm not able to maintain the whole).
