Do Microsoft Surface devices have this problem (the heat/fans spinning/high battery drain while sleeping, I mean)? If not, then Microsoft has no need to be embarrassed; it’s the rest of the PC laptop industry that should be embarrassed for not shipping hardware that does the right thing when the OS asks it to.
(Though, I mean, the rest of the PC industry should already be embarrassed, for still shipping new PCs in 2021 that don’t have Thunderbolt/USB4 ports, and desktop PCs that don’t even have a single USB-C port.)
There’s also the fact that Microsoft is (perhaps by accident of fate) “building for the future”; a lot of Windows 11’s assumptions in particular make sense given hardware and CPU steppings in mind that should have shipped a year ago, but which are caught in the COVID logistical conga-line and so won’t be seen for another year. That includes e.g. Intel CPUs with ARM-like big/LITTLE designs.
