Tell PG: "Pending" discourages conversation on older threads no longer on FP

I followed up with a reply answer to someone who, in turn, had asked me a question deep in a thread started a few days ago.

My comment is now in "Pending" mode and if that user doesn't have >1000 karma they are not going to see it and its unlikely anyone is viewing deep into the thread any more.

I'm wondering if this is an implementation oversight or an intended consequence to discourage conversation of staling threads?
