It's funny you say that because they just announced the introduction of ranges and I believe they return Spans.
Well, basic dataflow pipelines with implicit transfer of buffer ownership. So it is a language feature with implicit RAII lifetime management, which is why Span is limited to the stack. Then they have a counterpart to Span called Memory that can be stored on th GC heap.
A reasonable tradeoff, but a general constraint would have been more interesting.
