I actually found a reason why you do not want the .so symlink in normal 
runtime packages: If you have a library libfoo with different versions, 
i.e. 1.0 and 2.0, the libfoo packages for 1.0 and 2.0 do not have any 
conflicting files so you can in theory install both library versions 
(with same package name) at the same time. I don't know if debian 
supports this but I think on fedora it's possible to install multiple 
versions of the same package. Havin the .so symlink in the non-dev 
package would prevent this usage pattern.
