The
[Langfocus](https://www.youtube.com/channel/UCNhX3WQEkraW3VHPyup8jkQ/videos)
youtube channel came out with a new
[video](https://youtu.be/x9-e_3GHrzw?t=880) on Japanese. In it he explains
that the が can be used to express focus. I have never heard (probably not paid
attention) or learnt this. So, my question is: is this standard Japanese, or
rather colloquial use?

`ドーナッツが食べたい` instead of `ドーナッツを食べたい` to express focus on "donut"
