The critical point is that she was his partner not his wife, I believe that was the main reason why his Visa was refused. I don't think it was anything to do with the house sale.
I would imagine the reason for the delays is to try to get the costs down so the riders have to accept the deal if they want to ride whatever that deal is.
I have a lot of time for Stefan, definitely bags of ability , rode very well for Poole before and if he could stay injury free could have a very good season.
Personally I have no idea whether Keleher and Cook will be any good but it does seem the team has a long tail and I would agree that there should be at least one Brit at reserve.
Personally I have never had any issue with Havvy, great rider in his day, always pulled out all the stops for his country and nice guy to talk to in my own experience, judging by some comments others haven't had the same experience as myself but I can only speak as I find.
