I don’t disagree with the premise for very small applications, but

Means those will be nuked as soon as a new version gets uploaded. it really wouldn’t have been much extra work to put this into SQLite as well, and would lead to a much better user experience during updates

You are right, but i can roll updates during the night without causing any issue. Since after you finished playing you don't have a way to access your old games anymore

This isn't universally true.

I work on a telephony platform, some components of which need to be upgraded very carefully, because if you just restart the daemon without first transferring load elsewhere then you drop people's calls.

OK, there are less calls at night time, but there are calls all of the time and people don't expect their calls to randomly drop just because it's night time.

That works for the specific case presented here. As soon as you have users from other timezones, ”during the night“ becomes a really complicated concept quickly.

you are definetely right. :)

Can't you just serialize those things and then migrate them?
