Why does running pnpm uninstall produce a different lockfile than removing the dependency from package.json and running pnpm i?

I would have expected these to do the same thing but they seem to produce wildly different outcomes. If I run pnpm uninstall on our code base for any reason at this point, the lockfile produces won't work for any of our projects. However, if I remove a package and run pnpm i, the lockfile will remain stable such that we can keep building. One key thing I noted is pnpm i when removing a package from package.json doesn't necessarily rewrite the lockfile too much.

This is on pnpm v8 for reference
