It's by Larry Kaufman, so it's safe to assume it's for computer chess rather than humans. If that's the case, it's not a problem; engine matches are usually played as "game pairs" where each engine plays the same position as both White and Black.
Having unbalanced positions could even be better, as you'd be more likely to have a decisive game pair.
How big is hard to know. Maybe it doesn't matter much.
Chess engines can figure that out empirically.
PS I checked, and this has several mentions before April 1!
