Under the hood, cargo-embed, knurling's probe-run, and Humility are all built atop probe-rs (https://probe.rs/) to provide debugging - I think in this case it's actually a great example of cooperation between projects! Probe-rs has received PRs from both Knurling and Oxide devs; it provides the common interface to use various types of debug hardware and talk to various types of microcontroller cores, essentially replacing OpenOCD.
