Absolutely not. Adding a trickle to every underperforming building is horrible design.
Churches and Taverns have a build limit so it’s passable for them. In the case of Churches, the XP trickle is a good solution. In the case of Taverns, they shouldn’t have a trickle by default. It’s more of a bandaid fix that makes people build them, but not necessarily use them.
One option for more viable Livestock Pens could be to change the Ranching card to enable them to passively generate cows. And normally training cows could just be enabled by default in Age 3.
Pens could also maybe have a milking/shearing upgrade to let animals work at them like a shrine to generate food/coin.
