I would argue it is one of those things that is overstated due to
It is worth keeping in mind that explicit external schema is another
cost in not just designing but also maintaining the system. As such,
it is most useful for closely-coupled internal system, where one
controls both ends. This may be the case for computing pipelines a
single team owns.
Put another way: both benefits and costs of schemas accumulate over
long run, and the ratio ultimately determines which one wins. And yet
it is very hard to forecast in advance.
What can be said is that maintenance of no-schema is cheaper than
mainteinance of schema. Value of schema, on the other hand, is much
harder to estimate a priori.
