In an attempt to use subdirectories in the themes/<theme>/html folder, I discovered an interesting unexpected behaviour in the handling of the :layout parameter I thought I'd share. Metadata like {:layout :ignored/subdir/subdir2/template} will use the template at <theme>/html/subdir/subdir2/template.html oddly. I assume that ignored is set as the ns of the keyword, so a call of (name layout) ignores it.
