Maybe it would also be more user friendly, if QGIS would already deliver the grid shift files for most countries. But that would bloat QGIS quite a bit. The grid shift file for Switzerland (one of the smallest countries in the world) is already 3 MB. Maybe a grid shift file manager and repository would help for downloading, installing and deleting the files and for setting it up properly for easy usage.
Grid shift files are not always for free, and free ones might not be allowed to be distributed by others (like on qgis.org).
See https://github.com/OSGeo/proj.4/wiki https://github.com/OSGeo/proj.4/wiki/NonFreeGrids http://downloads2.esri.com/support/TechArticles/Grid-based_Transformation_Methods_for_Canada3.pdf for more details.
