I have a WD Blue 3.5" 2TB disk which does not seem to exhibit
this behaviour. Maybe an older firmware version prior to the
"green IT" move? I don't have Blue 2.5" (only SSDs) in laptops
so I cannot counter-check.

Get used to it - this will be the default of all "modern" items
you will be able to purchase. In worst case, they come with a
lower-level "know everything better than you" firmware that
cannot be accessed or controlled from the OS. It doesn' matter
if it's present in CPUs, mainboards, or hard disks; even cars,
TVs, desk phones or heaters can be affected... :-(

You can use smartctl to dump the capabilities and settings list
of a drive to verify that setting.

Why not? "Bricked by firmware update" is nothing unusual in our
"modern" "smart" time anymore. ;-)

If you put SSDs into an ATL and handle them like tape cartridges,
well, floating, sliding and spinning becomes normal. :-)
