Whether or not to use dolomite comes down to your compost to me. Most of it has plenty of Mg ready. For example, worm power vermicast has a 4:1 Ca:Mg ratio. No more Mg needed.
But if I did need Mg I would not hesitate to use dolomite.
Too much Mg will deflocculate your soil making it tight. Admittedly not a huge problem given our use of drainage amendments...but still no use for it either
