I don't know of another case like this, though I am sure there are ones which have not been publicised.
The faithful attached to the Traditional Mass in Croatia, not finding their needs met, appealed to the Pontifical Commission Ecclesia Dei, which took the matter up with the local authorities. And now it is announced that there will be a Traditional Mass on every Sunday and Holy Day in Zagreb.
Details on Rorate Caeli.
One thing to notice about the case is that they are not being given a monthly Sunday Mass, and less still a monthly or quarterly Mass on a Wednesday afternoon. This isn't about enabling a group of people to experience the Traditional Mass every so often. This is a Mass every week at 11.30am, to enable this group to fulfil their Mass-going obligations exclusively with the Tradtional Mass, and form their personal spirituality around it. The Mass is not a historical curiosity; attachment to it is a legitimate way of being a faithful Catholic.
