Looks pretty good. Not sure why you are doing a Version >NIL, but making Assign resident is a very smart thing to do, any Amiga age. PATH was good for making resident too, you wanted multiple paths to look for things that might be in different places.
I kind of remember 1.3 so vividly because it was always a big deal, getting things setup before the drivers got bound, on a bootable disk release. You could put the lines after that, but your LoadWB might not activitate properly unless things were set "just so" prior to that. Binddrivers was like a "glue in place" action.
WB 2.0 onwards was much nicer for that sort of thing, you might get error messages, but at least the system would startup, in some form or other. Getting a "LoadWB failed" error code and a DOS prompt was not a trivial thing, it meant I had screwed up massively somewhere already. L handler, Dev or library, setpatch, etc. Something was setup wrong.
I guess having an ENV folder was a key concept change. You wanted to tailor an environment, just use that properly. Nice idea, didn't always work, but it was a clear direction rather than a mess of spaghetti.
You could have your regular libs, devs etc in the "correct" place, and put any upgrades or downgrades in ENV and use that module instead. Saved a lot of deleting, copying, renaming stuff. Maybe that was the whole point of ENV. Most people didn't really use it, but they might have if somebody had oversight and direction of the issues.
