A foundation built like a tank is a desirable thing.
My only objection would be the surface grading, perimeter drainage, presence of underground springs, soil type, installation/conditions, or anything else that might compromise the integrity of the structure.
Example:
My father once built a tank house with an overkill poured concrete foundation.
Years later, a neighbor (several house down) forcefully drove in vertical beams for his new foundation.
Sitting on the second floor while this was happening, it felt like an earthquake.
Liquefaction.
The whole waterfront was swamp backfill.
