This question has been asked in the past. Basically the thought was to 
provide some sample wrapper functions that people would use as a 
template for building their solutions. While there are some common 
features that would be nice to have in the generic wrapper functions 
like trim the segments to the start and end points and being able to 
enter two lat/lon's, many of the customizations are problem specific and 
would not be valuable to others because they are solving a different 
problem or their data tables are different.

A good example is filtering pedestrian and bicycle ways from your bus 
routes. Oh and I don't use OSM data so anything OSM specific would get 
in my way. But there could be a collection of OSM specific wrappers that 
would be very useful to others working with OSM data.

For example I write new wrappers for almost every project I do because 
of these differences. IE: my existing wrappers do not fit the current 
problem I am trying to solve.

I think we would all agree that getting some of the common changes that 
everyone uses would be useful.
