Qt has already dropped their neard support for Qt 6 [2], which basically means the mainline NFC stack won't be supported anymore in one of the most common application frameworks for IoT/embedded.

Re: QT - I've already talked to Alex Blasche from QT (CC'd).  With some
work we can get Linux NFC/neard back into their good graces.  I/we need
to find time to put in the work, though.

An example of the issues they have seen is:

	https://bugreports.qt.io/browse/QTBUG-43802

Another issue I have--and I suspect you, Krzysztof, have as well--is
lack of hardware.  If anyone reading this wants to volunteer to be a
tester, please speak up.

To help get everyone on the same page, this is a response I made to
Krzysztof in another email:

    "Krzysztof, the NFC portion of the kernel has a counterpart in userspace
     called neard.  I'm supposed to be maintaining it but I have next to no
     time to do so.  If you have spare cycles, any help would be appreciated.

     Anyway, in neard, there are some simple test scripts (python2 - I/we need
     to update to python3).  The current home of neard is:

     git://git.kernel.org/pub/scm/network/nfc/neard.git"

Thanks,

Mark
