Personally, I definitely would. Disk space is not really a particularly limited commodity for me, and considering that VSCode's install footprint is already 200MB+, it's not really a problem. Of course, it's always possible to add some kind of setting for better intellisense, but I suspect most people don't really care too much about the disk size. What I would care about is performance impact/CPU usage. Another potential issue for me is if adding PVTS would force the extension to be closed source like the C++ extension. TL;DR: Definitely
