There is definitely a value to configuration files ... indeed, when Struts
first started using XML for configuration this was considered a huge
positive, for the reasons Vic lists :-).  It's only nowdays that XML config
is out of fashion.

That being said, there is a competing school of thought that revolves around
the idea of just building the actual logic of your application, and let the
framework figure out how to wire everything together.  For a framework to be
popular today (versus five years ago when Struts was working towards a
1.0release), it needs to recognize this desire.

Even if this proposal gets implemented, and even if it meant removing the
existing built-in support for executing a Commons Chain command mapped to a
URL, nothing stops you from using CoR yourself.  It's a few lines of code to
set up an action method that does what the current implementation does.
Indeed, the existing code from ShaleApplicationFilter.doFilter() does
exactly what you'd need to do -- it would just need to be recast into an
action method instead of as a Filter.
