I do not remember such a specification, nor do I believe it is even technically possible, and nor do I think it has been implemented that way.
Here is the "unit record" code:
L R5,PARM2 POINT TO MODE
MVC 3(1,R5),IOMFLAGS Pass (updated) file mode back
BNE NOTUNREC Not unit-record
OI 3(R5),IOFUREC flag unit-record
IOFUREC EQU X'40' DEVICE IS UNIT RECORD
Why can't we have a similar small amount of code for the "T" flag

Are you sure? It doesn't look like that to me. MODE is an input/output variable.
