Amusingly, I am going to have a BLOG OFF with Nick, where I argue in favour of “anyone can submit EIPs” – the group of people who review them is much broader than just Core Devs, especially as we boot up Rings. So, if it’s Wallet related, the people working on Wallet Ring can provide their expertise. More broadly, anyone can make a technical comment / objection to any EIPs.
Since it is fully open, lots of people end up making political or non-technical arguments, which is not helpful.
As I’ve stated several times, what you’re apparently asking for here is exactly the conclusion we came to. Please do get involved and help out.
PR issue: honestly, “we” are going to continue operating in the open with full transparency.
