In the case of the judgments of Python that the original article refers to, I can see ways that E-prime could help (because the criticisms might be phrased more concretely, like "Python 3 lacks the 'u' qualifier for strings" or something, allowing a reassessment of whether this problem was still true in the future) but maybe one could still say something like "its creators designed Python 3 hastily and sloppily without regard to programmers' convenience", which, if true or believed at first, never stops being applicable even if the language gets improved later on.
