qemu-img is going to switch the default for QCOW2 to QCOW2v3 (compat=1.1) [0]
Extend the probing for qemu-img command line options to check if -o compat is supported. If the volume definition specifies the qcow2 format but no compat level and -o compat is supported, specify -o compat=0.10 to create a QCOW2v2 image.

ACK,
Thank you; pushed now. Jan
Incidentally, it sucks that while we've solved the capabilities detection problem for QEMU avoiding the need to use -help or similar args, we now re-introduce the problem for qemu-img.
