The kicad-developers list is not really for detailed library discussions
like this. You may have better luck reporting the issue directly on
https://github.com/kicad/kicad-footprints/issues

I am not sure what the plan is, but I don't think the Librarians will
update the old footprints, all activity are done in the new repos.

> Hi!

> I've had a an unpleasant surprise with a 2512 (imperial) smd resistor
> footprint (Resistors_SMD:R_2512_HandSoldering) available in the Kicad's
> official library (shame on me for not checking the dimensions before
> sending the gerbers). When our boards arrived we verified that the pads
> of this footprint are too further apart, up to the point that the
> resistor barely touches the pads.
>
> I've looked on some datasheets and other sources and confirmed that this
> footprint is out of the recommended dimensions
> (http://www.resistorguide.com/resistor-sizes-and-packages/).
>
> I've attached an image showing the dimensions from the website
> above. The recommended dimensions for 2512 are a = 3.5mm, b = 1.6mm and
> c = 3.8mm, while in the footprint available on Kicad a = 3.2mm, b =
> 2.7mm (no problems with this been wider as it is a hand soldering
> variant) and c = 5.2mm.

> c       3.8         5.2 (too further apart)
