And apparently still doesn't. By a crude experiment:

//STEPLIB DD DISP=SHR,DSN=SYS1.LINKLIB,BLKSIZE=1
Worked fine.
Of course it did!
IEFBR14 has (effectively) two instructions:
SR 15,15
BR 14
NO open.
(But did I really test what I thought I tested?)
I don't think so, there used to be a minimum BLKSIZE of 18, but that's not
detected until you try to open the DSN.
No open; no error.
IEFBR14 does no open.
I think what he Gill was testing was that program fetch didn't care
about blksize, in which case I think he did test it, and got the
result I would expect. There may have been a time when program fetch
cared, but if so, I don't remember it.
By the way I think the 18 byte minimum was only for tape.
