#materialized_for_all_platforms ⇒ Array<Gem::Specification>

Materialize for all the specs in the spec set, regardless of what platform they’re for This is in contrast to how for does platform filtering (and specifically different from how ‘materialize` calls `for` only for the current platform)

Returns:
