This "fetaure" was not packman's idea ... 

see openSuSE-shared-library policy:
http://en.opensuse.org/Shared_Library_Packaging_Policy

and even jack2 is providing this scheme:
http://trac.jackaudio.org/wiki/SuggestedPackagingApproach

* "jack server frontend" - virtual package provided by "jackd" and "jackdbus" 
packages
* "jack server (library)" - package containing libjackserver.so at least. 
Maybe also: essential tools, drivers, inprocess clients.
* "jackd" - package containing jackd binary. This package depends on "jack 
server (library)"
* "jackdbus" - package containing jackdbus binary and jack_control script. 
This package depends on "jack server (library)"
 * "jack client library" - package containing libjack.so
 * "jack client library dev" - package containging headers and pkgconfig file 
for libjack.so
 * "jack server library dev" - package containging headers and pkgconfig file 
for libjackserver.so 

This shared library policy needs a lot of extra-work but it allows also to 
update library packages without breaking existing packages and or 
mass-rebuilds if a so-name of a library is changed (ffmpeg-libs, x264 are 
well known candidates for changing often API). 

And if we don't follow the naming-scheme of the base distribution we were lost 
and have much more troubles.

have fun
