what about Arexx in OS4 ?

Including the 68k ARexx?  Do you have a license for that?  

Remember, ARexx was a 3rd party add-on for AmigaOS that was licensed
by Commodore.  As such, it is not legal to include unless you have
negotiated a new license with it's author.

But they'd need to learn another language anyways, as ARexx was not a
proper REXX.  I realized that after coming from OS/2 to the Amiga.
While the origin is the same, there would still be a massive learning
curve.

I think the Friedens up there did the smart thing in picking Python
for AOS4, as it does fill the same need and is far more usable.  Not
the choice I would have done, but I'm more into ORB based setups.
