I guess it depends on how much integrity Corbyn has - there's no Brexit that doesn't have a negative impact on the economy, and the type of Brexit that was and is expected is one that reduces immigration to zero, which means the most financially damaging type of Brexit of the possible range. The fully priced manifesto counted on the countries finances being roughly in the state that they are today - that's very much not what would follow a thin FTA.
Therefore, if he'd gone full Workington Man Brexit he wouldn't have had his manifesto.
Of course, if he just wanted to win and fuck the truth (cf Johnson) then he could have embraced Brexit and his spending plans.
