I am completely missing the point of this letter I realize.. but
doesnt your "The Right Way" also hide all the complex things too. It
either does that or removes a lot of functionality that some admin
needs to complete a job in a slightly different environment... which
means enforcing that everyone's enviromental needs matches what you
are laying out. I have to cover 8 different field environments and
tasks that require that the same tools do something slightly different
each time. Now I can build 8 versions of the same tool that reuses 90%
of the same code or I can increase the complexity of the each tool to
cover all cases.
