Yes exactly - we’re using the lack of `aspect-ratio` as a way to detect older browsers. There are other, more critical, things we now using (e.g. [the optional chaining operator](https://caniuse.com/mdn-javascript_operators_optional_chaining)) which tend to be unsupported on browsers which do not support aspect-ratio.

Our list of supported browsers can be found [here](https://github.com/discourse/discourse/blob/main/README.md#requirements). We currently supports iOS 15.7 and above (which is supported on Apple hardware released from 2015 onwards).
