Being used to the real Visual Studio, I've always regarded VS Code as a disposable, low-investment casual tool: it cannot make use of the project and solution files of its big brother, it lacks major features (e.g. the remote debugger), it is also casually engineered (e.g. no proper extension configuration GUI and very loose file caching).
It's just an advanced text editor to edit files (of all types in principle, mostly Python, JavaScript and JSON in practice) and to make Git commits, not an IDE to base important work on; I've never tried to set up any sort of "project" or complex configuration.
As an end user (as opposed to an extension author or "open source" contributor) I'm not particularly worried about lock-in and proprietary features because the cost of not using VS Code any more is limited to switching to a worse editor.
