At the end of the day, Indexers will have a certain cost to run, and lowering that cost with complexity is a cost benefit analysis, do you want running Indexers to be cheap(er) and more competitive? and how much would you like to pay for that.

we haven't started with any of this anyway, but it is important to have plans for what seems as inevitable needs.
