I was a bit surprised they didn't opt to try and accommodate it in the 9pm hour on BBC1

When that happened in the past for various reasons, the 2100 ratings were very poor.

It seems the BBC has a '1930 Mon-Thu whenever possible, regardless of the channel' scheduling policy now. Next week for example it's on BBC2 Monday only, despite the relatively easy option of a double BBC1 episode on Tuesday (and moving the Tue 2000 programme to Wed when England at least has repeats)
