I do exactly the same, with a fairly simple awk script that maps pad width
to paste width and creates a temporary file, which us used as input to pcb
gerber export.

Indeed, but the script has the advantage, in this case, that all pads of
a given width get the same treatment, this is not always what you want,
but has been close enough for my use cases.

However I object to one attribute per footprint, because I have quite
a few footprints in which all pads are far from similar, or even close
in size, and need a different shrink value for the paste. These cases
are not limited to the center pad found below many packages for thermal
and grouding reasons.
