Thank you for your opinions. Another question I did not think about:

Right now, for multivariate polynomials, content returns the gcd of the
coefficients, even for non principal rings. For instance, over
ZZ['t']['x,y'], (2*x + t*y).content() returns 1.

This makes sense. Over base rings which have a gcd(), the content should be the gcd() of the coefficients.
