I think it can be added.

RFC 1738 calls backslash "unsafe" (RFC 2396 "unwise") character and says  
it must be encoded, so this change won't affect any valid URLs/URIs.

I've tested how browsers handle path in <img> tag:
IE6, Opera 9.2, Safari 2 translate "\" to "/". Camino (Gecko 1.8) and iCab  
3 translate it to "%5C".
All browsers leave "%5C" alone, meaning that this change won't stop anyone  
 from accessing resources that really contain backslash in the path (tested  
Apache2 on OS X 10.4).
