[...] maybe we could have an option added to the URL interceptor so that we can encode which path to use for the devcontainer like this:

https://devpod.sh/open#https://github.com/loft-sh/devpod?devcontainer-path=.devcontainer/somedir/devcontainer.json

(codespaces does it https://codespaces.new/srl-labs/srl-snmp-framework-lab?quickstart=1&devcontainer_path=.devcontainer%2Fdocker-in-docker%2Fdevcontainer.json)
