Simultaneously serve both plaintext (e.g., http://192.168.1.100:5173) and ssl (e.g., https://192.168.1.100:5173)

Currently, there doesn't seems to be a straightforward way to toggle between encrypted and unencrypted dev server hosting, short of commenting lines in/out at vite.config.js/ts.

But it seem to me the pain-free solution would be to simply serve both at the same time (by default even?): allow visiting encrypted https:// URLs while preserving their original unencrypted http:// URL variants.

Rationale: recent browsers (in particular: Chrome since half a year ago or so) make it ridiculously hard to specify a whitelist exception to not allowing self-signed/dummy certificates. Making it easier to fallback to unencrypted HTTP when testing such browsers makes dev life a little less painful.

Handling both http and https would involve two servers and would have to be supported from Vite itself (if the feature is accepted). I don't think there's much we can do from the plugin itself to address this. Maybe you can follow vitejs/vite#16350 which has a similar topic.
