I made this addition for myself, maybe you are also intersted in it.

We have strict criteria for the icons we distribute. In addition to the formal requirements from our guidelines, there are also informal ones: small size matters. Look at the chart below and find your icon.

I know it's not very fashionable to count bytes on icons on the modern web, but it still matters to me. One kilobyte here, another kilobyte there, and now only icons weigh a lot. This task is more time-consuming than it looks at first.

If you've added or modify SVG, ensure that each SVG file:

• Be less than 2048 bytes

From your CONTRIBUTING document. Is it outdated?

However, I got your point agree with that. I could reduce the file size to 713 Bytes. However, I'm not an expert in SVGs, there might be more potential for compression.

From your CONTRIBUTING document. Is it outdated?

Nope, still valid. Icons can be complex, so we need an extra size margin. In general, I don't review larger icons. It's a start, not a finish.
