Wikipedia[1] suggests they're a real thing, and have real-world uses.  I can
imagine that a big disincentive to installing them would be powering them,
although line power would probably be enough for one or two hops.  Getting
access to the line in the right places to install them might be a challenge,
too (or at least be somewhat expensive).  No doubt telcos also don't want to
install them because they can make a whole lot more money for less effort
by forcing customers onto wireless.
