Tony, Don’t get me wrong, I was a loyal fan of VSE for years back when I helped support an ISV product that ran on both the MVS and VSE of the day (way-y-y-y before z machines and systems, pre-XA in fact). We even supported the somewhat short-lived SSX/VSE packaging. That was actually a fun project to do. 4331 processor, 3310 and 3370 disk units. Good memories.
Life events eventually forced me into the "big OS" world but I still miss the nearly seamless integration of VM and VSE, and the tremendously flexible and powerful VM development environment. I always thought that IBM missed a big opportunity in stopping their promoting and selling of VM/VSE for the smaller shops, and instead abandoned them to other hardware and software vendors. Small shops may not be as profitable, but they can grow into your flagship business areas, but not if you don't have your foot in their door in the first place. IMHO the IBM CEO who told investors "we will always (implied: ONLY) be in high-margin businesses" was always a stupid rule to try to run a successful company by. If you don't have any path for potential customers to feed into your more profitable areas you have no customer base after a while.

First, a CA level backup/restore program for VSAM that was offered to z/OS but they turned it down. Much faster than EXPORT/IMPORT and even faster than CA-Faver. We have had it since the early 80's. Second, we support FBA and SCSI disk. Third, the JES2 support for virtual printers/punches is missing a lot of things that POWER on VSE supports. This causes me a lot of work when I do a z/VSE to z/OS conversion. Historically, we have had NJE over TCP/IP for many years before it was added to JES2. We actually had TCP/IP available on VSE before there was any offering for z/OS. We have had real data-at-rest, field level, automated encryption since 2006. (This is actually one of my products.) Yes, there is a lot of stuff z/OS has that VSE does not, but that does not mean VSE does not have some stuff z/OS does not have. BTW, it is my understanding that REXX/VSAMIO on VSE was written by Boeblingen as a white-room project that did not use any of the Armonk stuff. Boeblingen had a real sharp REXX developer back in 2001 (yes! 2001, 19 years ago). The z/VSE VSAMIO routine will even read/write CICS files via cross-partition communications using CICS as a FOR/DOR. And, it's all IBM code that could be ported to z/OS is the z/OS developers would get off their high-horses and ask for the code.
