Point taken, but I more or less consider this “static”. The distinction is artificial (of course there’s always a server behind the scenes), the question is just which server you’re programming against in the abstraction stack of the majority of your program. Hybrid approach often includes “incremental regeneration”, i.e. partial builds on-demand with caching. So that fits very well there. But it’s an implementation detail. The programming model you’re writing against can just use an “invalidate” function without concerning itself with the outer “actual server” layer.
