Yes, the more pastoral approach would be to address the issues with the person on a personal basis - as the key issue here is RECONCILING them back to the Church, not just banning them. Banning them only, is impersonal and offers no chance for reconciliation. What the bishops should be doing, in cases where there is a suspected problem, is speak with them. It is only then that the proper balance of doctrine and pastoral guidance lends the best chance of bringing them back to the Church.
This of course doesn’t even bring into play things like where’s the line on someone being “pro abortion”, that could get very messy. Example, people having been writing letters to the Vatican suggesting parishioners who should be banned from the Eucharist because they voted for someone who has exhibited some degree of pro-abortion behavior (ignoring the fact that sometimes both candidates are pro abortion in some form or another, and we are forced to pick the lesser evil). No matter what the definition, there is another person pushing the definition even further. This is another strong reason why the bishops need to be Shepherds of their flock and not policeman. And thank God this was the conclusion they reached. Now hopefully they will SHEPHERD!!!
