But generally the p2 metadata produced for a feature.xml will lock in very specific versions of their included bundles and features which prevents those from being updated to a different version.  That's sometimes annoying and then folks will use p2.inf information to specify looser requirements.  E.g., the platform uses EMF but in an installation of some Eclipse package/product the users want to be able to update/install a newer version of EMF.

I don't think using p2.inf is the more straightforward and sustainable (in term of maintenance) approach for that case.

A feature can define dependencies with the <import> element to add a non-version-locked dependency that will be installed together with the feature. This is better supported by PDE and Tycho than a p2.inf and keeps everything in the feature.xml (easier maintenance).
