we lobby for change while the lobbying is fruitful
there are just so many hours in a lifetime
some have to be spent actually getting something running

and Roland alluded to this:

its a different ballgame when you want something to work optimally

as possible on all systems

for the latter, one bad system can spoil the big picture, unless
you compensate with a well designed abstraction layer
