If IBM replaces REXX across the board, that would have to include continuing to support TSO. Also, those developing in REXX for TSO and ISPF environments would get a productivity boost if oorexx were supported there.
It's a moot point because it's never going to happen. 1. IBM are too busy porting contemporary languages like Python, Golang and Node.js 2. No vendor will port ooRexx because there is no market for it that is willing to pay support 3. The pool of REXX developers is shrinking by the day and no young people want to learn it unless they have to

I would expect IBM to functionally stabilize EXECIO unless there is something that it does better than stream I/O.How might stream I/O deal with RECFM=V binary files, particularly containing '15'x among the data? Many programmers insist on the superior performance of EXECIO * over EXECIO 1 in a loop probably due to CALL/RETURN overhead. linein() in a loop might suffer similarly. ADDRESS SDSF API provides generated DD NAMEs for spool files. I've used these overriding IEBGENER SYSUT1. I could imagine overriding SYSUT2 with a pipe which could be read by linein().
