Can't figure out if its a decision or overlook that buttons have [&_svg]:size-4 by default

I don't understand why we force-size a svg in this way, I delete it in all my installs, but I started wondering if its there by design, by decision or just a mistake that never really got handled. Because it stops sizing icons with text. Perhaps size-fit is more appropriate, or perhaps size-[1em]?
