Allow the "Venetian Government" tier 1 republic reform to be retained across tag switches

[Hezekiah]

I played a campaign as Venice for the Venetian Sea achievement and stayed Venice to try and complete the Venetian mission which grants +1 to the randomly generated doge candidates and to use the Subjugation CB against a large Austria. I played a long and annoying campaign, but stayed Venice instead of switching to a good nation. Unfortunately for me, now that I have completed all of the Venetian missions, forming Italy causes me to lose the Venetian Government. As Paradox has let the Prussian government persist from Prussia to Germany, I see no reason why forming another nation should force Venice to usurp her doge.

Please change the behavior of the tier 1 republic government reform "Venetian Government" so that it is retained across tag changes.

Not just the Venetian Government, but every government type please. It's more entertaining if everything isn't locked behind specific tags, culture, and/or religion. I understand it might be more "correct" or "historical", but if it I want to be (for example) a Byzantine Empire with the Ottoman Government, I should be allowed to keep that government type instead of being forced to change it upon tag switch. I'd even take maluses or negative events as a cost of keeping it.
