For Debian, we solve the dual-lived script program in the general case by using the packaging system's diversion facility, which lets one package move a file from another package out of the way. For perldoc in particular, we do exactly what you've described above; the 'perl' package installs a perldoc stub which invites the user to install the 'perl-doc' package for a full implementation (which then uses the diversion system to replace the stub). By the way, I am aware that we (Debian perl maintainers) should respond to some other parts of this thread; unfortunately we haven't yet found the time to do so.
