Hey @morisil! I had a PR (lppedd#3 - will re-create soon) waiting in line for #129, #130 and lppedd#2.

I see you've simplified the publication mechanism, I think that could be integrated after the KGP update.

Hey @morisil, most of the targets were enabled in #135. IIUC, only binaries.library() and swiftExport, present in this PR, are not yet on main. If you still want to see those targets, could you please rebase your PR on the updated main?

Also, automated dependency updates are already enabled on the repository level, so the versions plugin is redundant.

Note that those two functionalities should be enabled by library consumers, not by the library itself.

For example, binaries.library() is only useful if you're going to create an npm package.
