Thank you for the pointer,
I will move the discussion there.

Dear all,
I just noted the following:
sage: R = LaurentPolynomialRing(ZZ,'x,y')
sage: T = R.remove_var('x')
sage: T.inject_variables()
Defining y
sage: y in T
True
sage: y in R
True
As one should expect, now for a second try
sage: R = LaurentPolynomialRing(ZZ,'x,y,z')
sage: T = R.remove_var('x'
