Agreed that there is a middle ground.  Devices like these are something that customers can individually deploy on their 
lit fibers (then again, many optical
vendors now include automatic fault location (e.g. OTDR function) into their line interface cards with OSC add/drop 
filters (e.g. Ciena ESAM, etc).)

And ofcourse, I think it's great for carriers to deploy these on their own internal circuits for telemetry purposes and 
improve fault location response.

But as far as dark fiber pair that's being leased out to an end-user customer or another entity, I for one, do not want 
any carrier equipment whatsoever
on any fiber spans we obtain from another party (be it fiber swap with a carrier, or leased segment otherwise), full 
stop.   Everything else besides glass
is more attenuation to me, and with data center MMRs along the eway, there are already enough insertion losses as is.
