(19W13A) Illagers spawn way too frequently

I really like this new update and the ideas behind it, namely the Illagers adding a bit more difficulty to the game. What I don't like is how I can't go five minutes without an Illager Patrol trying to shoot and/or hack me open. The fact that Illagers can spawn pretty much any time any where as well as the fact that they may pack the overpowered Vindicators makes them feel more like an artificial difficulty inflator rather than a natural enemy that makes things a little tougher. Please, either A.) reduce their spawn frequency and/or restrict where they spawn to specific biomes, or B.) Make an item like a banner or an idol that prevents Illagers from spawning in a specific radius.
