No objections, it seems, go for it!

IIRC laptop-mode-tools can fix this if configured correctly,
but this is not the right solution IMO.

I'm not sure if this is a (common enough) problem for 3.5" (non-laptop) HDDs,
but it's worth noting that 2.5" (AKA "laptop") HDDs are used not only
in laptops:
Mini-ITX boxes, NAS boxes, HDTV players, even some servers - all have
2.5" HDDs quite often.
