8x8 and 8x8@2 emblem directories absent from index.theme

Some packages ship 8x8 emblems (here is an example, also I'm wanting to add some for my project). Whilst 8x8 is positively tiny, Nautilus does render emblems at this resolution when file icons are 16x16. Since 8x8 is so tiny, I am wanting to redraw my project's emblems (which represent the git status of files) at this resolution for better clarity. However, I am seeing that emblems placed in /usr/share/icons/hicolor/8x8 or /usr/share/icons/hicolor/8x8@2 are not used. Instead, I see downscaled versions of my 16x16 icons being used. I would like differently drawn icons at these two resolutions so this is not ideal.

The problem appears to be due to hicolor's index.theme lacking an entry for 8x8/emblems. Other icon themes appear to have these entries, and I can see that their 8x8 emblems work in Nautilus. So I think these entries should be added to hicolor's index.theme to allow packages to add 8x8 emblems to the fallback theme. Whilst we're at it, why not add 8x8@2 as well - tiny icons are more tolerable on high DPI displays, so the tininess of 8x8@2 icons is slightly less ridiculous.

If I made a merge request for this is it likely to be merged?
