Hello Paolo, Yes, indeed, this is the crux with italic fonts… It's hard (to say the least) to automatically determine whether or not the additional space inserted after "mf" is needed. Even in hot-metal typesetting the typesetter has to decide when to insert such an "italic correction".
The only feasible way out I can think of at the moment is creating new special padded dynamics rather than overwriting the original definitions and then deliberately choosing one or the other depending on the context, e.g. \mfbox as a padded version tailored for boxing and standard \mf in combination with follow-up hairpins. Or finding a compromise plus applying some box-padding so that one and the same re-defined \mf will work reasonably well in all circumstances.
