I don't think it's a fuss, Bruce. Unless the install command is given the '--no-recommends' option, openSUSE *does* install 
'-devel' packages that should not be needed. In my case it was over 300 total packages.

At least one of the 18 recommended packages, through its direct or indirect dependencies, is triggering the installation of 
those '-devel' packages. And, I think that zypper's dependency solver just might pull in unneeded packages.

I tried to do a reverse dependency search and found packages that were automatically installed, supposedly to satisfy a 
dependency, but for which there was no installed package that required or recommended it. So it appeared that there was no 
reason for it to be automatically installed.

Even though if openSUSE does have an issue, your post highlighted it which is helpful for us when creating the installation 
instructions for the OBS repo on the Wiki.
