(wazero contributor) thanks for the analysis. certainly dependency pain is something we hear about, as well as lack of maintenance on alternatives. Some don't release at all or rarely, and many break api constantly. We also break api, but then again we aren't 1.0 yet.

wrt performance, we do watch it closely, but we've not done benchmarks vs non-default settings in other runtimes. It is the case that the tradeoff of avoiding dependencies means any optimizing JIT would have to be written to make long running things faster over time... no one has contributed this, yet, and more folks are looking at short lived despite it being the case interpreters are a great example of long lived.

Concretely, we do keep track of relative performance (literally each commit in fact), and it isn't uncommon to find PRs including perf before/after.

here are some pointers if interested in digging in! there are certainly some things we'd lose at.

Thanks for the analysis and good luck on things!
