For DFN landpatterns the problem is, that the large center pad is very close to the outer pads. Slight misalignment will cause short-circuits. Extending the small outer pads will improve soldering, but will make it harder to place the device exactly in the center of the land pattern. So it may be necessary to move the outer pads and to shrink the large center pad. Maybe addition of special orientation marks for exact position of the device may be useful. So name extension like "XL", "+" or "M" which indicates enlarged footprints are not very good for indication of footprints optimized for hand soldering. Postscript "HS" seems to be good and is used by a few people, but may be confused with "Heat Sink". Should we use "MS" for "Manual Soldering"? I think "name_HS.fp" is not too bad, but maybe "name_MS.fp" is better?
