... snap-fit, glue, welding, staples, rivets, plastic push-clips, and any other assembly mechanism which undoing causes the device to be structurally damaged, cosmetically damaged, or necessitates buying new non-standard fasteners for each open.
General point is that the battery itself isn't so special compared to opening the rest of the device. Even on my i9500 with a standard "removable battery", the plastic clips which hold on the back cover have started to break off because they must have been designed for 20 insertion cycles. We don't need a "modular smartphone", we simply need assholes to stop "designing" them as if they're disposable.
Self-threading plastic screws aren't bad as long as you always back-thread them when reassembling. Soft thread-lock as used on eg Thinkpads is about the borderline of acceptability, and that's only because if you open your device enough you aren't really worried about a screw loosening over time.
