My proposal is to just allow adding a simple text file into the lib

Tomcat is almost certainly not going to do this unless the Java Servlet
Specification adopts this practice.
You can implement your own ClassLoader that consults a file for its
CLASSPATH and instruct Tomcat to use that if you'd like.

Hello Chris,
isn't that something what is happening before the Servlet Spec. comes on
the stage. So copy the JARs from the repository to the WEB-INF/lib
folder and than let the application start up as normally.
I played with a first implementation for Jetty as it looks like as I can
extend the application server without patching existing code. I haven't
checked if this works as well with Tomcat but basically the deployer
which is doing the unpacking of wars looks as well for a libraries files
and then copies first the jars before letting the application start.
By the way, the text file needs to be slightly more elaborated in order
to prevent name collisions of libraries.
