PS4: 
I'm not sure if I follow. You expect current users of Simics to adopt this?
Currently, with QEMU it's as simple as running `make qemu`. Are there plans
to make Simics as easy to use? if not, wouldn't it be better to teach people
about QEMU?
> i mean it is no harm to add more support to the platform for coreboot i guess?

Every addition also adds at least some maintenance overhead. I've often
seen redundant additions to be abandoned and bit rot.
> It is a nice addition as well. As it does have specific use cases (although quite limited): as Intel or silicon vendors usually use Simics for the RTL simulation before the actual silicon is available, actively used by the internal engineers for that.

Do they use QSP?
> EDK2 and Slimbootloader already have nice support for Simics:

And others have support for other open-source emulators, e.g. Bochs.
Still we don't add those, why?
