What did I do ?

I opened the game (2.0.11 (build 79682 expansion, linux64)) and tried upgrading an old Factorio map.
Mods when map was created:
* base: 1.0.0

Mods when map was loaded:
* base 2.0.11
* squeak-through-2 0.1.1
* elevated-rails 2.0.11
* even-distribution 2.0.2
* flib 0.15.0 ...

Hello,
I've created an account just to bump this topic.
It's a great suggestion, also it could be interesting to add an `on_alert` event to the API.
