Take the proclamations of the site you linked to with several pounds of salt. It is a very, very, very Western site run by converts from protestantism. The article in question is simply wrong and out of date. I also note that most of it is lifted from a college paper written by another convert from protestantism!
As for the office being essentially non-existent, that is likewise simply wrong. As I said earlier, I’ve met one; There is a deaconess in the monastery outside my maternal village down in Greece (I have never met her but I have seen her at vespers at the monastery). I have a cousin who is a nun at that monastery and she speaks highly of her.
I am not suggesting for a moment that you folks should have deaconesses. It is 100% your call. If what you get is what we have, I assure you it’s not a problem, but given the culture of the Latin Church and Western society, that may well not be possible.
Deaconesses are thin on the ground. There's a few in Bulgaria and Romania but that's about it. They have no liturgical function so we're talking apples and oranges here. The commission under discussion isn't about whether the Catholic Church will approve female odd-job assistants at monasteries. It's far wider in scope and its focus will undoubtedly be liturgical.
