"Better" is always "for what metric" but if nothing else having the source code to the stack is always "better" IMHO even if one doesn't choose to self-host, and that goes double for SigNoz choosing a permissive license, so one doesn't have to get lawyers involved to run it

While digging into their open source story, I did find these two awesome toys, one relevant to the otel discussion and one just neato
https://github.com/honeycombio/refinery (Apache 2) -- Refinery is a tail-based sampling proxy and operates at the level of an entire trace. Refinery examines whole traces and intelligently applies sampling decisions to each trace. These decisions determine whether to keep or drop the trace data in the sampled data forwarded to Honeycomb.

I wouldn't be surprised if that style of leak were more prevalent than one would expect. It's pretty subtle. But that link is the only such instance I'm aware of it happening to such a degree in crates I maintain. Maybe there are other instances. This is why I try to use `Box<[T]>` when possible, because you know that can't have extra capacity.
