Abrogate & "Abandon" Continence Obligation of Married Priests a Canonical Option (Dr. Edward Peters)

Dr. Edward Peters proposed 4 options for addressing obligatory continence for married clerics here:

Four ways to reconcile law-tradition and clerical practice are possible

I have avoided urging to the Church toward or away from any particular resolution of this issue. I see, however, only four possible ways to reconcile the current disconnect between tradition and canon law on the one hand and current clerical practice on the other, namely: the Roman Church can:

• reaffirm the unbroken tradition of perfect and perpetual continence for all clerics; or,
• reaffirm the continence obligation for all priests, but abandon it for married deacons; or,
• assert a temporary continence obligation for married priests (and possibly deacons); or,
• abandon any expectation of continence for married clerics (i.e., canonize the present situation).

The passage above was accessed today, March 15, 2017, and Dr. Peters's webpage on continence for married deacons was last updated on Jan. 16, 2017. 

It is the last of the 4 options that would allow canonical dispensation from continence of clerics (in this case, priests and deacons).

abandon any expectation of continence for married clerics (i.e., canonize the present situation).

The argument this abandonment position addresses is as follows:

ARGUMENT: Even if the tradition of "viri probati" includes ordination of married men (or deacons) to the priesthood, these viri probati would need to then undertake perpetual continence (i.e., no conjugal relations with a married priest's wife after ordination to the priesthood) as is the ancient tradition and canon law practice of the Western Church.

COUNTER-ARGUMENT TO OBLIGATORY CONTINENCE OF MARRIED LATIN RITE PRIESTS: However, just as married permanent deacons (viri probati) can be dispensed from the canon law requirement of continence, so too married priests of the Latin Catholic rite may and must be dispensed from the obligation of continence.

The perpetual continence discipline is not a matter of the Deposit of Faith and thus subject to pontifical change, even if it is true (as Dr. Peters's observes) that there is no basis for abandoning continence in the Roman rite Church's history.  (Perpetual continence does not appear in the Catechism of the Catholic Church, but perpetual continence does appear more so in the 1983 Code of Canon Law demonstrating that it is part of the Church's discipline which is changeable.)

Therefore, a Pope that allows Latin rite married priests citing "viri probati" could AND would need to decree dispensation from this canonical requirement of perpetual continence.
