I would ask, "Foundational to what?" There are many gifts given to the profit of all; it is for our, the Body of Christ's, edification. Each gift is important for the task at hand, for the purposes God has foreordained.
 
Ephesians 2:20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;

1 Corinthians 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.

"Foundational gifts were for laying the foundation for the church: introducing the Gospel to the Jews and the Gentiles, establishing the first congregations, and completing the canon of Scripture. "https://www.lbible.org/Message/555/Spiritual-Gifts-part-360-The-Foundational-Spiritual-Gifts

"Key to his argument here is the role prophecy played in the New Testament. Ephesians 2:20 says the church is “built on the foundation of the apostles and prophets.” There is an important implication: “The foundational role of the apostles and prophets points to the authority of their words, suggesting that prophecy in the New Testament has the same authority as prophecy in the Old Testament. If prophecy still exists today, it is hard to resist the conclusion that the foundation established by the apostles and prophets hasn’t been completed, and that the New Testament prophets are still adding to the foundation of apostolic teaching.” He also shows that it is a mistake to distinguish between the prophet and his prophecy as if a true prophet can bring a false prophecy—something continuationists must permit.

Sometimes theologians divide spiritual gifts up into “miraculous” and“nonmiraculous,” with the miraculous gifts being tongues, healing, prophecy, miracles, interpretation, and knowledge. We however prefer to view the gifts under three categories: foundational gifts, nonfoundational gifts, and gifted men. In Ephesians 4:11 Paul writes that Christ gave apostles, prophets, evangelists, and teachingpastors to His church as gifts. According to Eph. 2:20 the apostles and prophets were foundational gifts upon which the church was built, thus when they died they took their function with them. There is a difference of opinion as to whether the gift of evangelism has continued in the life of the church, or whether the only gifted men that remain from Paul’s list in Eph. 4:11 are the pastorteachers.

The foundational gifts are the gifts that relate to the giving of divine revelation to guide and instruct the Church during the apostolic age. These gifts, such as tongues, knowledge, prophecy, interpretation etc. are the “miraculous gifts” that were no longer necessary once the Church reached maturity and the Canon of Scripture was closed (I Cor. 13:8-13)."
