Read the following passage:
For decades, geophysicists operated under the classical plume model, which posits that narrow columns of hot mantle material rise from near the core-mantle boundary to form intraplate volcanic hotspots. Recently, however, plate-tectonic theorists led by Dr. Elena Vance have proposed alternative models explaining hotspots entirely through upper-mantle shallow processes and lithospheric tension, suggesting deep plumes are an unnecessary hypothesis. While Vance's team rightly highlights the seismic inconsistencies and thermal anomalies that classical plume theory struggles to reconcile, their total rejection of core-mantle heat flux seems overly hasty. High-resolution seismic tomography has increasingly revealed deep mantle conduits under several major oceanic swells, indicating that mantle dynamics are far more heterogeneous than Vance's uniform shallow-source model admits. Thus, while shallow stress field variations undoubtedly modulate surface volcanism, discarding deep-mantle plume contributions wholesale risks obscuring the complex, multi-layered nature of planetary heat dissipation.
Evaluate the following statement based on the passage above:
The author's attitude toward Dr. Vance's position can be described as qualified skepticism, acknowledging the merit of Vance's critiques of classical theory while considering her complete rejection of deep plumes to be premature.
