Apropos of this discussion, I found the following:

Following the lead of six of his predecessors in this century,
Pope John Paul II recently decided to leave his own stamp on the
next papal election. On February 22, 1996, he promulgated "On the
Vacancy of the Apostolic See and the Election of the Roman
Pontiff," <Universi Dominici Gregis> (UDG). This apostolic
constitution minutely describes the procedures for electing the
264th Successor of Peter.
Like the steward who brings from his storehouse the old and the
new, the Holy Father both confirms and modifies previous electoral
legislation. Most of UDG restates Paul VI's rules of 1975 set out
in <Romano Pontifici Eligendo> (RPE). John Paul didn't intend, he
says, "to depart in substance from the wise and venerable
tradition already established."
In outward appearance, the next papal election will look very much
like the two of 1978.
The pope himself draws attention to three traditional norms that
he reaffirms with only minor changes: those dealing with the
composition and seclusion of the electors and with the secrecy of
the procedure. The near-millennial custom that the electoral body
"is composed solely of the cardinals of Holy Roman Church" remains
in place. While Paul VI was preparing RPE, he seriously considered
the possibility that bishops from around the world should vote in
papal elections. Ultimately, however, he declined to reverse the
nine hundred-year-old convention. Despite continuing pressure to
change, John Paul has confirmed his predecessor's ruling.
Solid theological and ecumenical reasons argue in favor of this
practice. First, since the pope is not the bishops'
representative, his election should avoid creating any such
impression. Just as the other apostles did not choose Peter as
their head, similarly the college of bishops does not elect the
pope. Second, ecumenical sensitivity supports the tradition.
Insofar as the Orthodox are willing even to discuss the papal
ministry, they need assurance that it is the Bishop of Rome who
carries out this office. How the pope is elected should mirror
this link to the See of Saints Peter and Paul.
It is entirely in keeping with collegiality and ecumenism to have
representatives of the Roman Church-the cardinals- choose their
own bishop. By designating them as the papal electors, John Paul
makes clear that the pastor of the universal Church is not elected
directly by the college of bishops over which he presides.
Instead, the local Church of Rome selects its bishop who is, ipso
facto, head of the episcopal college and visible head of the
Church.
UDG emphasizes that the cardinals are the appropriate group to
elect the Bishop of Rome. Except for patriarchs of Eastern
Catholic churches (there is one at present), the other cardinals
are all specifically bound to the Church at Rome. Six of them are
bishops of the dioceses surrounding the city. The rest are
incorporated into the local clergy by being given a "titular"
church, a parish in Rome where they serve as a kind of honorary
pastor. This Roman connection preserves the tradition of the early
Church that local clergy, with the help of nearby bishops, chose
their pastor.
At the same time, the international character of the college of
cardinals guarantees that representatives from churches around the
world take part in electing the pope. Today the cardinals come
from more than fifty countries, thereby providing the diversity
that gives papal elections a truly catholic dimension.
