+Early workarounds to fix build with upcoming Qt6.7.0 not to have
+to wait for the matching PyQt6-6.7.0. Not fully correct fixes,
+but should be better than failing. May need revision given 6.7
+apis are not finalized as of the writing of this.
+
+Caused by the following commits:
+https://github.com/qt/qtbase/commit/fd48ce0b73c (qdatastream+pyqtpyboject)
+> qsizetype is ssize_t and ends up more correct (e.g. for Py_ssize_t)
+https://github.com/qt/qtbase/commit/7a3fed3f209 (qtimezone)
+> removed, can just drop these if 6.7 and ignore the replacement
+https://github.com/qt/qtbase/commit/19bc5de296a (qfont)
+https://github.com/qt/qtbase/commit/bde443801fe (qfont)
+> these tag features are new'ish (and changing) and only available if
+> >=6.6 as-is, let's just drop them if 6.7 as no revdeps should need yet
