Now that I've spent a few ineffectual hours too many trying to get it working, I'm starting to think VS Code wasn't built for the purposes I wanted to use it for. I still can't get breakpoints working anywhere close to reliably. And I'd say breakpoints are pretty important.

On a related note, if anyone here has used VS Code together with arm-none-eabi-gdb, I'd love some pointers. I've yet to find any traces on the web of people doing that…
