Substitute Docker for another container technology, or even "IOT device" in my comment if that helps. The point i'm making is not about the size of the binary, size or type of container that it runs in (if at all), but about the features it can/will support if you rip out glibc and replace it in a fit of rage with musl or similar which seems to be somewhat of a fashion at the moment.
