I'm moderately hopeful that the basic idea (close association between activity and cost) will improve, but I have some caveats.

One is that not everything will fit. Lots and lots and lots of workloads exist in their current form and are not going to switch overnight. Whatever bookkeeping method that gets developed needs to deal with the mix of costing models.

Another is that you still need to assign costs. In a lot of companies this is the subject of intense corporate politics. Whether such a method is adopted will depend on who is wielding what cudgel.

Related to which: there will be cases of premature optimisation on the visible. Optimising for cost is fine, but costs often include estimates that can be overlooked. It's one thing to optimise for "least dollars spent per invocation". Another thing to optimise for "fewest pissed off customers". The latter is harder to measure but in many cases more important.

But overall? Yes. I think it could be a step forward.
