BIP 2 supplies for feedback that may be posted on BIPs at the Bitcoin.it wiki. These days, all feedback about BIP 39 are detrimental, which is what’s summarized as “unanimously discouraged for implementation”. All this is wanted for that abstract to switch is for any individual to put up a favorable remark.
Now, the feedback mechanism appears to be just about totally deserted, making the abstract probably old-fashioned with fact. I do suppose it might be higher if it was once dropped for this reason, however thus far, no new BIP has outdated the mechanism of BIP 2.
Finally, so far as the contents of your personal (obvious) opinion is going, observe that evaluations in opposition to BIP 39 are no longer essentially evaluations on the whole in opposition to all seed segment primarily based mechanisms, and under no circumstances evaluations in want of sizzling wallets (as a result of one could have chilly wallets that aren’t BIP 39 primarily based).
