I would have expected that alignment errors is something that can happen more often and ist more short-lived (basically alignment can be re-established quite quickly). Also, it's something you can actually count, as in 'how many frames with alignment errors did we see'.

LOS on the other hand is something that I would expect to persist for a longer amount of time.  Somebody disconnects a cable (intentionalyl or not).  It's unlikely this would only happen for one or a hand ful of frames, but more like seconds, minutes, hours.

We can of course change it, and I'm not saying I have a very firm opionion, just explaining my reasoning.
