IMO that is beyond what pkgsite is meant for. - versioned, package documentation.
The pkgsite renders README.md, so you can add the info there if you really want.

pkgsite already links to Open Source Insights, they show imports and imported by, they show license. Why not also link to places to fund the project? It could be under same Links section as "Open Source Insights" is.

But I think having it also be integrated into cli, same as npm has it, would even more improve the package ecosystem.

That's even worse, we don't need ads in more places

Open source insights presents information about the specific version of the package, mostly computed based on the information listed in the spec. Moreover, most info pkgsite shows won't change over time (maybe except vulnerabilities, or deprecation status). I am not sure if the state of seeking fund is a property of a versioned package. Even the package owner can change over time.

But I think having it also be integrated into cli, same as npm has it, would even more improve the package ecosystem.

Unlike npm or other language toolings, go commands try to stay quiet unless there is an error or problem that prevents operation. I don't think go cli is an appropriate integration point. If you want to change it, it should go through a proposal process and strong community-wide support.

Closing since this is beyond the scope of pkgsite.
