How to scale SVG without changing stroke thickness?

Question

SVG

I want to make a universal placeholder using svg.
So far I have done this: https://jsfiddle.net/kb8Lvw6u/1/
The problem is that the line thickness jumps. Is it possible to somehow scale the svg while maintaining line thickness without scale? Using js it is clear how to do it, but I want to do it without it.

It turns out there is a special crutch for this: https://developer.mozilla.org/en-US/docs/Web/SVG/A... .
