I must say, I'm thoroughly impressed that the Amiga community sticks with and improves the standards that were already set in the early 1990's (AmigaGuide, the Lisp-y installer scripts, LHA, and probably also things that are not mentioned in the article, like AREXX and datatypes) instead of reinventing the same wheel over and over.
Datatypes in particular are amazing! I really wish some of these features (see also: ASSIGNs) made it over to other platforms. Which makes me think... A really nice hack (after I finally port SetCmd back to 68k and then bring it to more platforms) would be to add an ARexx port. Rexx itself is a pretty decent scripting language and the ubiquity of it on later-day Amiga systems meant that glue-ing components together and automating big chunks of platform behavior was very simple. Off down the rabbit hole again ;)
Also have a long list of projects to make my Linux desktop more Amiga-like again...
