Received approval today for my 60 day Single entry TV, even though I put 89 days which my return flights are for.
I will still buy a cheap exit ticket from Thailand before the 60 days expire, just in case there are any questions at the UK departure.
But at least I will save a few hundred pounds from changing the ticket dates from 59 to 89 days, as I found to my cost last year.

They plan to purchase a cheap exit ticket to relieve potential issues at UK departure. Comments indicate that a 60-day tourist visa does not legally require a return ticket, but having one can ease check-in situations. There are discussions about the potential for changes in visa policies by the new government, alongside inquiries about extending the tourist visa.
