Abd ul-Rahman,
        a footprint without associated paste mask detailing is only an
incomplete solution. It's like having the PCB without components or a
soldering iron to attach them. So everybody goes off into their corner and
duplicates their time and efforts to prescribe and describe the paste mask
for each and every footprint design? This would probably lead to footprint
designs which had not considered paste mask or varying levels of paste
deposition during the design.
        What was the point of this thread? I think you may have overlooked
the obvious, that is the footprints should be a complete solution for all
and eliminate duplicated individual effort.
        To this end the solder paste mask deposition should be specified
from the start and the whole library designed to work with that deposition
of solder paste. Otherwise you do nobody any favor if one footprint works
with 4 mil solder but the one you choose to locate directly beside it was
meant for 7 mil solder deposition.
