{When to stop \dots} {Hans Hagen} {A flexible system like \TeX\ permits all kind of solutions for (weird) problems, so as soon you run into a special case it is tempting to come up with a solution. When many such solutions are built into a macro package at some point they start to compete. How far should one go in being nice for users and customers, especially when demands are mostly based on tradition, expectations, and of course subjective, non-rational and disputable artistic considerations? An example is a new optimization available in some \ConTeXt\ mechanisms: profiling. Do we really need it and, if so where and when does it need to be available?}
