Maxweightrating:hgv and Truck profile


Do Graphhopper support openstreetmap maxweightrating:hgv tag?
Week ago I edited road and added maxweightrating:hgv=16 tag for a road but it is still used by Graphhopper “Truck” profile.
Now I noticed this tag is in proposal status, so started to think maybe it is not supported.
Truck profile weight limit is written 13000 + 13000. Does this means 26t always or in some circumstances it is 13t?
Thank you for your help

Yes, this tag is not supported.
