This appears to be using a simple file watcher based on glob patterns to detect changes [0] so I'd be curious if we can configure that list to include ViewComponent instances as well! That may be harder since it's not just a static asset, and the keys in the config do appear to be hard coded [1] so I think each asset type has some quirks around how it can be hot reloaded.
