Where used publishing

Dear All,

We have been asked to create a workflow robot to navigate up a structure and publish the where used of a item. The rationale for the client is they make some changes that do not affected the form, fit and function and so do not change the part number but want to re-publish the where used items, one reason is to ensure the visualisations and tech pubs are upto date (apparently they have issues that the manuals are sometimes out-of-date). Technically it is not difficult to do but clearly this might, in some cases, create alot of publishing jobs and before we implement a technical solution I just wanted opinions on if this is a sensible thing to do, or the client should re-evaluation their processes.
