I also use my own set of footprints.
The reason is that footprints need to be compatible with the production
technology.
When you run with solder paste, stencil, oven, be capable to position
precisely enough, then you can go with short pads.
For soldering with iron, or if you are not very expirienced with hot air
repair you better go with long pads.
The structure is still a mess and very often I just run an editor to
extract footprints from known good older designs.
