I'm always a bit confused by "written in X" as a feature. Rust devs are the worst about this, but not the only offenders.

The language is not a feature!

I'm a C++ programmer, and even I don't care what language the applications I use are written in.

"Fast" is a feature, not that it's in C++

It's a way of signaling a feature via implication - if it's built in X which is known for Y, it must be Y.

What the imply it's that it won't be a slow app built with electron.
