Don't think it's going to be about the Ukraine conflict, they didn't know about the Ukraine conflict when they announced the pack as there was no Ukraine conflict back then. Also, it takes a lot of time to plan their art and designs, so don't think they will rework an entire kit into some sort of Ukraine statement.
If we go by the dictionary definition, to the max means to take something to the greatest degree, so extra to the max would mean to take it even further than that. I imagine it's like a houseparty kit for teens with no parents who get to turn the music volume all the way up, so the neighbours call the police and they show up in highheels with a stereo on their shoulder because the neighbours accidentally called an exotic dancers entertainment group called "The Police". By the time the real police shows up, the pool is already filled with foam, sprinklers are on, there's a bear sleeping on the couch, Mr. Goth is making out with Bonehilda in the upstairs dresser and Mrs. Goth, Mrs. Pancakes and Mrs. Landgraabs are dancing sexily in their underwear on the dining room table.
