But the serial-port plug that pi-bluetooth declares is not auto-connected. I created a snap removing the daemon declarations, so bt* are normal commands. I could install it, and then I connected the plugs, including the serial port with:

$ snap connect pi-bluetooth:serial-port pi:bt-serial

Then I could run successfully the commands:

$ sudo pi-bluetooth.btuart
Flash firmware /lib/firmware/brcm/BCM4345C0.hcd
Set Controller UART speed to 3000000 bit/s
Device setup complete
$ sudo pi-bluetooth.bthelper
hci0: Routing SCO packets to HCI

So to fix this we need to ask the store admins to add an auto-connection for the serial port to the snap declaration. Not sure how this was working in the past though.
