I think the problem might be that only "j71sap" but not "j71tap" for iPad6,11 is in libirecovery/src/libirecovery.c

I added {"iPad6,11", "j71tap", 0x10, 0x8003 }, to irecv_devices[] in libirecovery.c and built everything from scratch. It fixed the problem and let me restore form 10.3.2 to 11.1.2.

Alright, but to clarify: The issue persits within libirecovery which is used by idevicerestore which is used by futurerestore. See: https://github.com/libimobiledevice/libirecovery/issues/38

It is now fixed in libirecovery!
