No. It is my expectation based on earlier discussions that fractional 
numbers were added namely for LaTeX. I used leading dot in 
\includegraphics[width=...]{}, so I was surprised that Org ignores it. 
Explicit "+" is just generalization, this form is supported by LaTeX and 
elisp.

Above #+attr_html does not specify :width while #+attr_md has a valid 
value. It is the reason why I do like current behavior.
