rpm spec file “Suggests” statement

Question

I am currently refurbishing a lot of outdated specfiles, and I remember talking about soft dependencies, which would come in handy for a current specfile (i.e. lighttpd suggesting the most popular modules to be installed, like mod_rewrite, mod_redirect).

My main issue is, google seems to fail to release any bit of valuable information on the implementation status of the Suggests: statement, its current overall status and rpm version requirements. Most documents and howtos are from 2004 and earlier, too outdated to be considered a trustable source. The absolute rpm pdf does not state anything about the Suggests: tag either.

Thanks a lot for any information in advance.

Post scriptum: OpenSuSE & Mageia seem to use it, but beyond that..
