Not at all (speaking as a long time researcher of marine accidents,
currently, the Titanic).

Running aground to avoid sinking and buy time to control flooding is a
time honored technique that has saved many vessels.

When a vessel becomes severely flooded, loss of stability and capsize
become a primary danger. The ability to control attitude in seas to
diminish the probability of capsize can be a life or death issue.

No argument there. But then nor does it have the constant
horsepower drain
that pump incurs.

The beauty of that system is the very low horsepower drain. When
functioning as a blower, the loss would be insignificant. It isn't
going to be a very effective blower at shaft rpm speeds but it should
keep a constant, very low, flow going.
