there is a fair amount of code using small exponents like 2 or 3 where it
is expected that the result is still integer. I would like more input from
users than we have seen so far...

Just to highlight this, if anyone wants to strengthen the argument for
switching to float then this is something you can literally do: tweak a
local checkout of numpy to return float from int**int and
array-of-int**array-of-int, and then try running the test suites of
projects like scikit-learn, astropy, nipy, scikit-image, ...

(The reason I'm phrasing this as something that people who like the float
idea should do is that generally when proposing a risky
compatibility-breaking change, the onus is on the ones proposing it to
demonstrate that the risk is ok.)
