What is the real reason behind Maple Leafs placing goalie Cayden Primeau on waivers amid goaltending shuffle?

The Toronto Maple Leafs have placed goaltender Cayden Primeau on waivers following the return of Joseph Woll. Primeau, acquired earlier this season, posted a 2-1-0 record with a 4.30 GAA and .838 save percentage in three appearances. This move allows the team to manage their goaltending depth with Woll back and Anthony Stolarz performing well.
