My only fear is if there is, or will be, a way to write Linux software explicitly requiring to be run under it.

That'd be the Extend step of EEE.

Although, I strongly doubt it'd come to that. Not because I think the new MSFT is above EEE, but because I think it'd be hard to pull that off with the community of Linux software writers and users.
