Again, Philip was not a leader in the Church. If I baptize you and someone writes it down. Does that mean it is now God's will?
Here's some data on Baptism...
The question we must ask, and answer, is why did Jesus command his disciples to stay in Jerusalem? It was to wait for what the Father had promised, i.e., the gift of holy spirit. The disciples had already been baptized in water. If water baptism was all that was important and necessary for salvation, there would have been no need for the disciples to wait in Jerusalem or receive the gift of holy spirit. Sadly, many people reverse what Jesus said here in Acts. They say water baptism is essential for the believer and act as if baptism in holy spirit is not really essential but perhaps “nice to have,” or valuable in many ways. Jesus was teaching quite the opposite. He knew the disciples had already been water baptized. He also knew it would no longer be intrinsically valuable after the Church started on the Day of Pentecost. Thus, he commanded his disciples to stay in Jerusalem and receive baptism in holy spirit “because” John [only] baptized in water, but holy spirit was going to be first poured out in Jerusalem.
“with water.” The Greek is hudōr (#5204 ὕδωρ) in the dative, thus, “with water.” Thus it is clear that the element that people were baptized with was water. However, in the later part of the verse, the specific word “in” (en, #1722 ἐν) is used, emphasizing that the Christian is baptized “in” holy spirit. There is one baptism for the Christian, and it is spirit, not water (cp. Eph. 4:5). John’s baptism was a shadow of what was to come, and even John himself said this (Matt. 3:11; etc.). There is no reason to baptize in water today. Nevertheless, the practice continues, and sadly some even teach that it is necessary for salvation. [For more on baptism, see John Schoenheit, The History & Doctrine of Christian Baptism (Spirit & Truth Fellowship, 2011).]
“in holy spirit.” The Greek text has no article “the.” This holy spirit was the gift of God that He gave to some believers before Pentecost. [For more information on the holy spirit and uses of “holy spirit,” see Appendix 11, “What is the Holy Spirit,” and also see Appendix 6, “Usages of ‘Spirit’”].

Whether or not it was in God's will is a separate point.
