It would be quite surprising. Many Reformed people have been very positive about A Kempis and the Modern Devotion. Are you aware of the book
Sweet Communion? It traces the connections between A Kempis and Bernard of Clairvaux into the Dutch Second Reformation. Many of them reprinted The Imitation, sometimes editing it to "reform it" as it were. They also wrote their own books around similar themes.
Calling it a theology of glory is strange, do you definitely not remember any context for where you read that?
