In my own experimentation with Qt icon scaling, I have found scripting ImageMagick or Photoshop to do the up/down-scaling, with or without a bit of sharpening applied afterword, to produce better quality icons than the Qt scaling. It may be good enough quality to preclude re-creating your icons for the other sizes.
If the results are better, it can be simple solution.
Another option is to design icons with fewer details and higher contrast so that they still look OK when scaled (see MSSQL icon in Giovanni's QGIS example). I believe this would also address the issue of some icon groups looking too busy due to too much detail, example: the 'Add * Layer' icons of your set.
This is only matter of decision and use of simpler version, without "layer" sign. With bigger raster/vector/WMS/etc.
Having multiple size sets for icons means some naming conventions and coding to switch between the sets; whereas now, the code simply asks Qt to handle the scaling by setting a toolbar's icon size in one call (as an example). Another good reason to go with icons that can cope with Qt's scaling: no code changes.
Different folders could be solution if Qt's scaling won't work?
Switching between size sets also means any third party icons (e.g. plugins), that don't provide multiple icon versions, will have their icons scaled. This would end up with users seeing different quality between core and plugin toolbars, though I don't know how much this can be avoided regardless of scaling issues.
This is very important argument in favour of one SVG file.
So, my vote here for your icon set would be to go with only the 24x24 size, reduce the complexity of the most complex icons, increase overall contrast where needed, and add any 2.5 effects to make them pop a bit more (but not if such an effect causes the blurry scaling problem or poor quality to occur).
