Not sure about the legal situation but there appears to be a lot of deep technical diving happening in Croatia. I'd like to try it myself (within my limits) next time I visit.It is hurting someone, Tec diving is not a big industry in Europe. If someone decides that 5 dead people in a lake is enough it is perfectly reasonable to prohibit tec diving like in Croatia, where every recreational dive over 40m is 100% illegal.
Luckily no one cares at the moment for the most part, but a number of caves and wrecks are closed (and monitored) due to it.
Wrecks - Krnicadive diving center - Krnica - Pula, Istria
In this area there are more than hundred sunken ship wrecks. This days we dive 15 to 20 wrecks in different depth range. Starting from 30 meters down to 85 meters depth.
