Both attempt at doing this:
- QGIS at
https://github.com/qgis/QGIS/blob/master/src/core/providers/ogr/qgsogrproviderutils.cpp#L1172
to #L1230 when it closes the last connection instance of a GPKG file
- and OGR too :
https://github.com/OSGeo/gdal/blob/master/ogr/ogrsf_frmts/sqlite/ogrsqlitedatasource.cpp#L367
Probably the most reasonable & simple change for QGIS would be turn WAL
only when QGIS update mode is turned on. Would require testing that
deadlocks don't occur with existing readers prior to turning WAL on (or
accept that risk...)
