Yes, please lift the restriction. I ran into this issue while writing a testcase as well. As J3 is not considering unsigned for F23, I believe that you needed worry about whether this should be hidden behind GFC_STD_GNU. You may want to ping Peter Klauser to see if he's inclined to also lift the restriction in flang. This would prevent incompatibilities.
