I think the reseller site is a good development and I use it a lot.
My issue is that my wife has long covid so her health is really up and down. Sometimes she will pull out of attending the game on the day of the match due to fatigue (long journey to Bmth doesn’t help) but the club aren’t interested in reselling within 2 days of the game.
I have gone to the ticket office early on match day and offered them to resell the ticket and not give me a refund as it’s a sunk cost for us. However, I was informed it was too late to do anything about it.
If I have longer notice that she won’t attend it’s good to see someone else attend, who otherwise would be able to see the match, and see them enjoying the game.
