Wow, meldmerge is awesome. It has Github integrations and syntax highlighting.

There is a difference between IBMs Python port and Rockets. Rocket have patched Python to use fopen() so it supports the MVS file system. There are also other MVS libraries such as a load module call API, IDCAMS, BPXWDYN etc. IBMs port will of course become dominant so as Matt said get those RFEs in.

BTW, I noticed in the z/OS 2.5 announcement IBM made the following statement of direction. This will be a game changer. At Rocket we have moved a lot of development over to the file system so we can use Git and DevOps tools. This new file system will enable customers to use tools like Git without having to migrate their code. For COBOL that's pretty much a must have.

*New file system support to access z/OS data sets*

IBM plans to provide a new file system type that will render traditional z/OS data sets accessible by the z/OS UNIX name space. This will enable z/OS UNIX applications, tools, and utilities transparent access to data in these data sets in a secure and consistent manner.

More seriously, I would add a couple of points:

- Whether or not you like Python or think that it is weak tea compared to REXX, 
you should support getting a good Python implementation on z/OS.    Our 
favorite platform will be more attractive if it runs popular languages - and 
Python is king these days.

- Python isn't perfect, but it is seriously nice.  This judgement is based on 
the amazing software that I have seen written in it.  Try one example:  Meld is 
a terrific FOSS visual diff / merge tool that is multi-platform and written in 
Python.  Try it out and then look at the source code.  https://meldmerge.org/

- I agree that Python on z/OS could use some native libraries to do z/OS 
interfaces like REXX.
