It's useful for shiny hunters who want a specific species, but like you say is largely a negative when you're looking for new stuff like Pansage or Grubbin.
Also, I'm gonna guess Niantic fucks up this mechanic on August 13th, because 2pm to 7pm local time will feature 4 star raids with Galarian Linoone, and the promise of additional Galarian Zigzagoon spawns if you complete the raid.
The "Kricketot spawns" and "Galarian Zigzagoon spawns" for raid completion bonuses conflict.
