Most icons are used along-side text, like the top bar or menus. It therefore makes sense for them to adjust along-side the text when the text-scaling changes. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/995
GNOME Shell Sass
GNOME Shell Sass is a project intended to allow the sharing of the theme sources in sass between gnome-shell and other projects like gnome-shell-extensions.
Any changes should be done in the GNOME Shell subtree and not the stand-alone gnome-shell-sass repository. They will then be synchronized periodically before releases.
