(Article author here) Agreed! Instead we passed a law locking the size of the House at 435 members. And the present political interest in changing this seems limited at best.
Interesting point, though: smaller states end up at the extremes of both over- and under-representation under the current system (though there does appear to be a systematic bias in favor of small states). I wrote about that in a previous article: https://l.bit.io/census-apportionment-bias. Larger states tend to be close to the national average constituent-to-population ratio while smaller states are more likely to be very over- or under-represented.
