Technically, the different packages should only offer the same
implementation of an interface if they make it available in a public
place of the run-time environment where it is found by default by all
components which may require a given implementation. General examples
for such places are the dynamic linker's search paths for shared
libraries [1], Perl/Python module directories, and most likely similar
directories for Mono and other programming-language run-time
environments. If, however, they store the implementation in a private
directory, where it doesn't satisfy run-time requirements by default,
they should not advertise the implemented interface [via the RPM
system]. It bears the risk of breaking other packages like with this
Perl module example: http://bugzilla.redhat.com/247113

[1] The automatic SONAME Provides are a smoldering fire, since by
default the soname for any lib in a private path is provided by
a pkg, leading to dangers like: https://bugzilla.redhat.com/278181
