I know there is a wide range of icon fonts and they still have advantages over SVGs, but often you only need a few icons within a font but it still needs to be loaded completely. Creating an own icon font is always a bit more work. Adding an SVG would be so much faster and you would also have the possibility of manipulation via CSS, if they were inserted inline and not within the image tag.
The icing on the cake would be a built-in minification or cleanup of the SVG code, to save detours via online tools… just dreaming
Let the builder allow us to select svg files from media library. For sanitization we use a different plugin? This is important to keep the website size smaller. Some times I use 2-3 icons from each library that will make all icon libraries to load.
