Not exactly. In the current system only xaw-wrappers has the
responsibility to divert the files and keep track of them. In my
proposal, the individual packages have to supply the conf files and
have to call the register and unregister scripts on install and
deinstall. xaw wrappers has only to supply the scripts and call them
on  xaw-wrappers install and deinstall. 

In the current system it could happend that a package moves a binary
(as it happened with xdvi) and so brake it unaware that xaw-wrappers
is installed. With my proposal, tetex-bin would call
xaw-rwappers-unregister in postrm and xaw-wrappers-register in
postinst. So there would be everything fine.
