Allow cross-platform/per system initializeCommand definition

[Destroy666x]

Not sure if it's the most proper repo to report this (if not, please redirect), but would be nice if there was a way to define initializeCommand per system in any way, so that the setup is truly cross-system. For example:

"initializeCommand": {
  "windows": "rd /s /q somedir",
  "linux": "rm -rf somedir",
  "macos": "..."
}

Use case example: https://stackoverflow.com/questions/77199011/how-to-create-a-cross-platform-initializecommand-for-visual-studio-codes-dev-co (copying proper .env file before container launch).

Thanks for filing! I believe this would also be related to (and potentially covered by) #58, #405.

Potentially indeed - assuming "features"/"things" include initiaizeCommand. If yes - looking forwards to that.
