This is not out of choice.  :-)

We have an XML config block that currently builds an interceptor chain based on config options.  In the same XML config, adding more custom interceptors before/after this chain is easy, but to modify the chain is hard - imagine some XML element like:


  | <suppress-interceptor interceptor="org.jboss.cache.TxInterceptor" />
  | 

or 


  | <replace-interceptor position="2" interceptor="my.custom.TxInterceptor" />
  | 

Very ungainly, and presumes that the user knows what sort of chain will be generated.

And, as you said, open to a lot of breakage.  :-)
