2 remarks about that:

• generally I think it's better to wait until triage is an issue because of the volume or missing info (we'll know what info to ask for)
• it's now possible to define a form instead of just markdown sections if you prefer, see https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository#creating-issue-forms

I agree with your first remark. However, as Dune Package Management will be soon in ocaml.org, I wanted to make sure we don't have more triage work to do than expected. If people are coming from the Dune Preview (from ocaml.org), I wouldn't expect this to be mixed with the general dune maintenance 😕

About the second point, I have seen it but as it was in beta I was a bit cold to introduce it in Dune. WDYT,
