anssiko has just created a new issue for https://github.com/w3c/battery:
== Assess compatibility risk of using [SecureContext] ==
If we'd add `[SecureContext]` to `partial interface Navigator` and `BatteryManager` as is the current trend, we could drop the following prose:
>If the current settings object is not a secure context, then reject this Navigator object's battery promise with a "SecurityError" DOMException and abort these steps.
However, this would break any feature detection code that relies on checking the existence of properties or objects, e.g.:
```
if ("getBattery" in navigator && "BatteryManager" in window)
console.log('All your battery are belong to us');
```
I guess nearly everyone using this API must do some sort of feature detection.
My hunch is we want to close this issue as won't fix citing backward compatibility concerns.
Thoughts?
