I have seen that in recent svg files, there were still some sub-images, temporary objects apparently, which are outside the icon but still there in the svg files, though, no more useful nor used.
Here is an updated set of files, to replace those in src/src/resources/images/svg. This does not change the behaviour of the icons, just slightly reduce the size of the files.
This has been obtained with inskape and saving them as optimized svg files. I have also transformed dbginfo.svg to use path and not text for the integrated i.
