It simply wouldn't work for lower league clubs. Frankly, I also fear for the Owls future viability if they now were to perform like (say) Ipswich and remain outside the Premier League for 15 years or longer.
If I understand this correctly, you buy a ten year Premier League Season Ticket now, and your seat is free until it kicks in. If Robby Cowling offered this I would bite his hand off as it would give me an eternity of 'free' seasons.
Wednesday must be desperate for cashflow now as this is a gamble on promotion. Frankly, if I ran the EFL I would not permit it. I see nothing wrong with an all divisions ten years ST, but this is madness. It could take them twenty years to get promotion.
