I’ve not had a spool come apart but then I’ve only used 6 or 7 spools from Bambu. I have noticed that some Bambu spools are not wound well and look like they will have the trouble you describe. And so far, every spool from Bambu has been wet enough to drive the humidity in my AMS way up. It’s solved by drying the spool but of the dozens and dozens of Overture filament, I’ve not dried a single spool. One Bambu spool of Support W was so wet it saturated the desiccant, requiring it’s replacement.
