The intention of the heter was for the husband (or a messenger) to literally travel all over the world to present their case and get 100 Rabonim to sign on. Even in the easiest of cases (e.g. where the wife is in a vegetative state or disappeared a number of years ago and hasn’t been seen since) the traveling itself can be cost prohibitive. In this case, where the wife clearly hasn’t disappeared and isn’t in a vegetative state, on top of the traveling the person also has to present his side of the story and the Rov will try to contact the wife who will dispute everything he says. This will make the process significantly longer if at all possible.
Part of the cherem is that the gett can’t be forcefully given and there may be places where someone will walk into a Kollel and as 100 Yungeleit to sign on but it’s probably not universally accepted.
