I've made a private MacPorts port[1]; if I find that I use it frequently enough, I might contribute it to the main MacPorts port repo[2].
One thing that's missing from my perspective (and this is probably true for Homebrew packaging as well, but I don't do that) is Git tags / GitHub releases associated with your Cargo releases.
I can work around it for now by using an explicit release (`9ccd9bf53f9a309ccda42b5c17e9c1056493fb90` is what I'm assuming was your 0.1.0 release point).
I've also assumed that npm10 is sufficient (which currently installs node22 on MacPorts).
