This would enable people who want to publish a Quarto project to Pages to set up their workflow quickly and easily from the GitHub marketplace instead of having to write some YAML from scratch. We can also support some features that may be out of scope for the official Quarto actions, e.g.: Setting up Jupyter/Knitr; setting up a fully custom dependency environment with Conda, Pip, or other package managers;
We should open a ticket with the Quarto team to see if configuring dependency environments is in scope for their project, in which case we can contribute our efforts there. Also, the current Quarto actions do not meet the requirements for publication to the Marketplace, and I'm not sure if that's something they consider a priority.
