Realise that this means more recruiters and it being a hugely valuable service all of a sudden, whereas today it is maybe neutral on the average (helpful for some, annoying for most). Since random strangers on the internet couldn't be trusted in this possible scenario, recruiting firms could be the ones to build up reputations of having suitable/legitimate candidates. You might not realistically be able to get around them.
More middle (wo)men does not sound like an improvement. But to be fair, I don't really know what the deal is with cover letters. When applying to a job, I always write some text in the email that explains why I can do that job and why I'm interested at all, it's not like I just drop my CV on an email address and trust the recipient to take it from there. The application process may be different in NL/DE versus whereever OP lives, or for my line of work compared to theirs.
