The main difference with probes is that you can carry a ton of these things at once. They could also be made available to all ship classes, rather than just scouts. So, while it's not indredibly useful, it seems a fun enough thing to try.
Chat can be easy to miss especially in pick-up games or when dealing with spam. It often *is* missed, even by vet players (I see this all the time). Also it can be hard to describe something via chat sometimes; i.e. the precise co-ordinates of a point of interest. Also, if you're, say, probing your sector for TP2 scouts, and suddenly get eye, you might well be low or out of probes. One rack of these beacons could be enough to help track down the source of the eye.

This also seems like a very good reason to me.
Anyway, this addition can help teamwork, and is another way for the team to communicate, so it's hard to see it as a bad thing in the least. Except if it locks up one of those "def" things that we decide we really need or something technical like that.
