That must be a fairly recent development. I never seen that
and I visit Kings Cross every few weeks. Obviously this will be
helpful for passengers needing to decide from which station
the next train will depart.

Not just the next train, but the first to arrive at their destination. For
example, it shows that there's a train boarding on platform 10 for
Cambridge, but there's one 10 mins later from St Pancras that gets to
Cambridge eight minutes earlier.

Do they hide trains from St Pancras that are insufficiently soon?

"too soon", perhaps. They certainly won't be using the normal published
'interchange time' which is 30 mins (although perhaps that's 15+15)

Yes, just seen a St Pancras Service disappear from the board at Kings
Cross 15 minutes before its scheduled departure from SPILL

Seems sensible. I suppose 10 mins might just work, but 15 saves people from
having to rush, possibly crossing the road unsafely.
