yes, it reboots without play services. You may need to execute the code again after an update (when nor only disabled bloat is reinstalled but often new bloatware too is pushed without your consent)

from my experience none of my apps broke, only get some annoying please enable google play services notifications from whatsapp, and embed google maps also breaks, suprisingly my bank app works fine, havent had any issues beyond this, survives reboots but I havent tried updates as my phone doesnt receive those anymore and the rom scene for my model is non existent
