This is also my perspective, as someone living in Italy although vaccinated elsewhere. IMO, the 6 month rule was a reaction to Omicron, pushing people to get their booster, especially the older who were the first to get vaccinated (some 6+ months ago), as well as those who took Astra-Zeneca. At the six-month mark for most, which will begin in early May for the first to have been boostered, the government will either align with EU prescripts or the EU will begin pushing 4th doses. TL/dr, don't worry about this until about one month out.
