Updating vim packages can be a nightmare if you don't vet your plugins and generally install stuff "just in case I want to try it out later". If you aren't using a plugin with any regularity, delete it.
I don't know what vscode's plugin architecture is like but I imagine it's just that Vim's is extremely powerful and, you know, with great power comes great responsibility and all that. Unfortunately, many vim plugin authors are not responsible, or don't realize they aren't being so.
