There's not what I would consider a definitive specific reference, but
in several places (including the Initialization & Tuning Guide) note
that the maximum LRECL for INTRDR and SYSIN data sets is 32760.
Somewhere (but I can't find it right now) there's an explicit
prohibition of RECFM=U, and I'd also go along with VBS not being supported.
Note that the MVS Assembler Services Guide still documents that the
maximum of instream data is 254 and JCL records must be exactly 80. I
haven't tried larger than 254 yet…I should add this to my little INTRDR
toolkit program.
I just tried a VB/255 data set for a SUBMITLIB as a test and it worked
perfectly.
If you're thinking about PROCLIBs, though, those don't work, they must
be F(B)/80.
Cheers,
Ray

Curious, I did a search and found:
<https://www.ibm.com/docs/pl/zos/2.5.0?topic=consider-jes2-disk-reader-support>
...SUBMITLIB ... The concatenation supports any format PDS (LRECL and
RECFM) that
can be used to pass JCL into input processing.
That assertion is a nullity: It supports any supported attributes. Where are
those
explicitly listed?
