As a self proclaimed Centrist, no the problem is not being in the middle of things but that each side typically more nuance than most sides are willing to concede.

Promotion of a Nordic Model of Economy is still an embrace of Capitalism, Laissez-faire fundamentalisrs will decry the government oversight & taxation, and Socialists will decry the lack of workers/community owning the means of production. Meanwhile the nuance looks at the efficacy of capitalism while mitigating the worst consequences.
