Not what I meant, heap allocations are allowed (although the stack should be preferred if possible), but ideally only with long lifetimes and stable locations (e.g. pre-allocated at program startup, and alive until the program shuts down), and you need a robust solution for spatial and temporal memory safety, like generation-counted index handles: https://floooh.github.io/2018/06/17/handles-vs-pointers.html).

Yeah, I feel like we work in completely different realms of programming. Which is fine; there are plenty of languages out there for all kinds of use cases. FWIW, pre-allocation absolutely doesn't work when you support loading GB-size datasets. You certainly can't leave it sitting around forever either once it is loaded.
