I'll plant my lawn sign to lobby for support. I think this is such a completely new way of running a shell it's worth investing in to see how far it can get.
Maybe I am a computing retrofuturist, but I like anything that pushes towards a Plan 9 / Smalltalk / Jef Raskin like dynamic, configurable, adaptable, programmable, textual user interface.
Also, recognition is always better than recall. I hate the UNIXy command line. I have limited brain capacity and I don't want to lard it down with knowing that it's ssh -p but scp -P. If this can help with that, awesome.
