Agreed vis a vis SHIFT. cligen also has a global config file [1] to control syntax options like whether '-c=val' requires an '=' (and if it should be '=' or ':', etc.) which has been discussed here, various colorization/help rendering controls, etc. Shell scripts can always export CLIGEN=/dev/null to force more strict and/or default modes.
