I can only assume that is not the reason.
It shouldnt be for the club to pay a player, to get fit and find another club, if no fee is involved.
That is for any prospective club to spend money on him, the Dev squad is to offer opportunity and experience for contracted players to advance for BHA.
I think you're focusing to heavily on the finding another club point. It's benefiting us as well as it looks like we need an extra player.
Plus the wages he'd be on would be very low anyway. You're looking at something like £250 a week in the dev squad and it's only for a few months.
