[Qgis-psc] [Qt-for-Python] report of the technical group

[Anita Graser]

Dear Denis,

Thank you for the report from your meeting. It is good to see the
discussions advancing further.

the next block to bring a broader set of tests in QGIS core running with
PySide (under Qt6) so the group could meet again, reevaluate the
decision and potentially propose a follow up

done by OPENGIS, it makes sense in terms of efficiency that OPENGIS also
handles this block (other devs might get involved in the potential next
ones)

investigation of using Qt-for-Python for QGIS’ bindings.

+1 from me.

Regards,

Anita
