I think it's a great idea--and fits well with my plan to make
default/default-wide full-fledged user-selectable themes that are
available in both 16:9 and 4:3 versions.
I'd been wanting to recommend a switch to Steppes as the new
default--since it's a great theme and, TTBOMK, the only one that's
available in 16:9 and 4:3 versions--but since its design wouldn't
necessarily "fit" well with other theme styles/designs (since it's not a
neutral style with traditional design), was afraid that it would be too
different from many of the other themes to work as a good fallback.
This would allow themers to choose a more-appropriate,
more-closely-designed fallback, even if the default/default-wide themes
were useful/pretty/non-neutral/non-boring themes.
