Certain data structures are much easier to implement using static arrays (for
example, object pools with statically-sized chunks).

You mean TLS?

Arrays in the data segment have a fixed address. This means that arr.ptr is
actually known at compile time (whether the language exposes it or not). arr[5]
involves no address calculation at all during program execution as well.

BSS does not bloat executable size, only virtual memory.
