2.7.X Themes - Some New, Some Gone

I noticed a “refresh” of the themes between the 2.6 and 2.7 series of releases. I’m particularly pining for Bantai’s OS R theme, being the only theme which allowed me to keep on truckin’ when the sun shone directly on my screen. Is there a technical reason it got dropped or can I load it in from an older release?

By all means, you are free to use the older schemes.
I don’t know if they work as nicely as the new ones. 2.6 didn’t had the layering options etc so don’t know if these options will be badly affected or simply ignored.
But i suspect you have to manually adjust here and there for the new areas in 2.7
