why we made this limit.. Its not compatible for even newer

Does this really work for you? Even when skipping the version check, I cannot install nrfutil because recent pc-ble-driver-py releases do not have wheels for Python 3.11.

ERROR: Could not find a version that satisfies the requirement pc_ble_driver_py>=0.16.4 (from nrfutil) (from versions: 0.1.0, 0.2.0, 0.3.0, 0.4.0, 0.5.0, 0.6.0, 0.6.1, 0.6.2, 0.8.0, 0.8.1, 0.9.0, 0.9.1, 0.10.0, 0.11.0, 0.11.1, 0.11.2, 0.11.3, 0.11.4)

Just a side note to @robin-nitrokey comment - Im getting the same issue on python 3.9 running in cygwin - the pc_ble_driver_py wont install - its returning unsupported wheel format. I can, however, happily use the windows version of python3.8 with the newest nrfutil 6.1.7. So the latest nrfutils I can install in cygwin is 5.2 and that is not compatible with python3 (xrange / range issue).

At this stage im happily running python3.8 on win with nrfutils 6.1.3 in cmd shell. I would much rather to use cygwin though :)
