| MUST: If a package contains library files with a suffix
| (e.g. libfoo.so.1.1), then library files that end in .so (without suffix)
| must go in a -devel package. 
Based on just the ReviewGuidelines, some packagers and reviewers
still get this wrong and create -devel packages for plugin .so libraries.
In particular because it is a MUST. The linked Packaging Guidelines page
on "Devel Packages" makes it a SHOULD and also mentions a rule of thumb,
but apparently this is still not clear enough.
How about this?
MUST: If a package contains library files with a numeric suffix
(e.g. libfoo.so.1 or libfoo.so.1.1), extra care must be taken to
distinguish between libraries needed at run-time and libraries
needed only when compiling/building software. Library files needed
only at build-time must be put into a -devel package.
