I’ll go ahead and predict that this turns into a confrontational situation before the school year ends in the summer.
At some point, some wise-ass kid will figure out the whole template required for walk-out protests, and start to organize save-the-Leprechauns, or save-the-Bigfoot walk-outs, and the school system will have to finally say ‘enough’. You only have X-number of days per year for education and this walk-out adventure (if you did it two or three times a week) will make a mess.
That actually sounds like a great idea to end this nonsense. At some point,the schools will have to ban all walkouts or be sued for discrimination. Fight fire with fire.
