That could always mean on mobile parts. I don't know how that's possible on desktop.
That's why my original post was about the different requirements of the desktop platform, I was wondering how they would tackle the use of SMT on the big core vs. firing up a small core instead.
The point of my latter replies containing slides related to Alder Lake and Lakefield was to prove that Intel already has the software (and hardware) in place to prioritize foreground tasks (unless they've been lying about Lakefield all along). The common part of the hybrid problem that they share with Apple is already addressed.
Moving away from that though, in high performance systems, Apple doesn't face the same problems as Intel when it comes to hybrid chips. First, they lack SMT, so their priority list is quite simple. Second, if the rumors are true, in performance chips they prioritize big core count over small core with a ratio of 4:1, so ensuring consistent performance won't be much of an issue, if any at all.
