We're running out of flags - does it make sense to have merge any of these flags at all?

Maybe that makes sense, however, I'm not sure which options can be combined.

I'm unfortunately not seeing anything we could do to make this better; I think it's the case that we can use up to the full 32-bit range, so it's not a problem now, but...

I believe that for 64-bit versions of Node.js that's the case; but 64-bit Electron may have different rules due to its pointer compression encoding (see microsoft/vscode#151245). If I've read this V8 blog post correctly, under that mode an SMI doesn't get a full 32 bits.

If Electron behaves differently, maybe we should be testing it; I bet it'd be straightforward to create a builder that does an ELECTRON_RUN_AS_NODE=1 or something (and even use @vscode/test-electron to grab the latest VS Code and run it).
