[Qgis-developer] Can I change QgsAbstractGeometryV2::fromWkb signature ?

I've been watching memory corruptions happening during WKB parsing 
and found the internal QgsAbstractGeometryV2::fromWkb method not
taking a size parameter to allow preventing such memory errors from
occurring. This needs be changed before it spreads too much !
The current method is virtual:
virtual bool fromWkb( const unsigned char * wkb ) = 0;
It'll need to be changed to take a size parameter.
Is that something we can do for this upcoming release or should
we just hope all our WKB providers will pass us good WKB ?
Note this all started from OGR giving a WKB which may even be
considered valid but our parser did not expect (3D components
inside a marked-to-be-2D collection).
