As an embedded developer I have different view. Linux is everywhere. I've been working within nothing but embedded Linux constantly since 2005.
I regularly install debugging tools onto target devices (strace, tcpdump, ...) even though those don't go into a production image.
Currently, I'm using pw on an embedded system, for capturing detailed traces from an application. It's very useful because it decouples the rate of the traces from the serial port, while still letting me get the info I need out of it.
The stripped executable is tiny: 20 kilobytes. It's so small I'm stashing it in a configuration flash partition which survives re-flashes of the kernel and filesystem, so I have the utility there no matter which image I load onto the target.
