Not a complete one, but I think some eastern factions gets new bodyguards and the KH get Greek Pikemen. I think might be some more but I don´t know the exact units. Anyway, the reforms trigger when a city with the hidden Italy resource becomes a Huge City, which ususally takes ages in my non-Romani campaigns. Also, Rome itself doesn´t have this resource.
The Sweboz reform could also be called a mini-reform, as I believe it only gives 1 single new unit, does Heavy German Cavalry dudes.
