P.Schm.....Again sure, in context Wis of Sol is not messianic, but it certainly lent itself to that interpretation.
The debates about exactly how the Teacher of Righteousness of Qumran was perceived will probably continue. It's not surprising. It likely followed a path toward mythologizing common at the time. What we do know is that he was identified with the S.S. The "Self Glorification Hymn" has been tentatively identified with this T of R by a number of scholars. If this is correct then we have a complete example of a Jewish individualized interpretation of the S.S. followed by heavenly glorification similar to the Enochic tradition in which the human prophet is elevated to become the 'son of man'. Even if this text was a reference to a future Priestly Messiah, we have a collection of ideas that seem to predate (or contemporary) the Christian concept.
