I've been considering that, and I think we are better off without
splitting -append in semihosting mode because this is at least
consistent with MIPS machines in QEMU (in non-semihosting mode) --
pseudo-bootloaders in MALTA and Fulong2e have hardcoded argc to 2
(-kernel and -append). Therefore I would leave it as it is unless we
really need to change it.
