Consistency. Each of the .yml files is effectively a complete (but
very small) drawing - It's a drawing that can't be subdivided any
further, but it can be opened and edited independently.
So a yml entity might say "I'm a circle with 10mm radius and I live
at these coordinates" - This is similar to a jpeg file: "I'm a
rectangular bitmap 11.111 inches wide, 8.333 inches high and I live
at 0, 0".
Another way of looking at it is that all files/entities in the
directory "root" are to be treated as part of the drawing directly,
sub-directories can contain other stuff:
1. Entities that may or may not be referred-to by elements in the
drawing itself (such as linetype definitions).
2. Other drawings that may or may not be being used as blocks or
'paperspaces'.
3. Miscellaneous resources that may be referred-to by elements, such
as text files and images.
So your way of seeing embedded bitmaps fits into (3) quite well -
Though I would keep these bitmaps out of the "root" as they would
then be implicitly part of the drawing itself.
