Maybe for bike-specific lights that cost in the 3 digits.
I use an el-cheapo cree zoomable-head, single-18650-battery affixed to my bars with interlocking hose clamps. So (a) it never comes off, and (b) if it did, it's made for knocking around in pockets etc, so it would be pretty hard to damage it.
