Hundreds of redundant icons installed on Linux

Seen in /usr/share/icons, in Ubuntu 20.04:
https://packages.ubuntu.com/focal/all/libreoffice-common/filelist

or libreofficedev7.0-freedesktop-menus-7.0.0-0.noarch.rpm


1) Easiest change with the biggest impact is to not duplicate icons 
from the hicolor theme into the defunct gnome theme:

https://gerrit.libreoffice.org/c/core/+/93712


Are the locolor icons used? Not duplicates but can they be completely 
removed?


2) SVG icons are installed in the fixed size directories

e.g.:
/usr/share/icons/hicolor/48x48/apps $ ls -w 60 libreoffice-*
libreoffice-base.png libreoffice-impress.svg
libreoffice-base.svg libreoffice-main.png
libreoffice-calc.png libreoffice-main.svg
libreoffice-calc.svg libreoffice-math.png
libreoffice-chart.png libreoffice-math.svg
libreoffice-chart.svg libreoffice-startcenter.png
libreoffice-draw.png libreoffice-startcenter.svg
libreoffice-draw.svg libreoffice-writer.png
libreoffice-impress.png libreoffice-writer.svg

These SVG icons often look like the source for the PNG icons - they are 
different at different sizes and not just scaled. Could just ignore on 
installation. But the scalable/mimetypes SVGs appear to contain 
multiple sizes of icons - unless that is a special format?
