Implementing mouse cursors as a hardware sprite isn’t that uncommon for 2D accelerated graphics, albeit later than on the Amiga. Something like an ATI Mach32 has one for example. About 15 years ago I had a crappy Dell whose Radeon card would randomly glitch the cursor, so it survived at least until then in newer systems. The extra responsiveness is more of an Amiga thing though.
