Commodore never upgraded Paula chip (knowing that company they probably immediately fired designer and didnt keep documentation to the chip), every model got the same 1985 state of the art Double Density floppy controller all the way to 1994 bankruptcy. As LIV2 already mentioned even their top of the line $3.5k A4000 Workstation shipped with gimped Floppy subsystem.

The floppy drive could read/write high density 1.76MB disks. I know, I had one. You're right that the Paula chip wasn't upgraded to handle double the data rate from the drive. The solution instead was that the disk span at half the speed.
