The suggested RFE is that RECFM be allowed so that a job can contain a mix of F 
and V in-stream datasets. Of course, that's only if there's a business case.

Indeed.  Suggested RFE:
Simply allocate the INTRDR with attributes same as the input file.

Strangely, LRECL is accepted on DD *.  It appears to have no effect.  (Verify
by experimenting with SYMBOLS=JCLONLY and extending a record.
I went to SR with this; REJ USER.)
RECFM is prohibited.

But empirically, I've found it more complicated:
o If no record image exceeds 80 bytes, SYSIN appears as FB,80
o If all record images are equal length, SYSIN appears as FB.
o Otherwise, if JES2 SYSIN appears as VB.

I've not found documentation of this; I may have submitted an RCF.
