I actually agree with you: He is under no obligations whatsoever. None. But I still am allowed to plead my case to him, for him to decide as he wills, and to spread the issue and discuss it so that the best possible solution can be reached.

As to programming something like that: I am willing to personally implement something like that if asked, although I was more thinking of the manual method of those who want access PMing Yvain or his designated representative and asking for access. Again, I am willing to have the burden of such a task placed on my own shoulders, should Yvain agree. I honestly am trying to find a solution, and am willing to invest a fair amount of personal effort in this.

About the reposting: Yes, I agree. However, there was a lot of stuff on the old blog. Literally thousands of posts, and it would be impractical to repost them one by one. A possible alternative though is for Yvain to repost them en masse, simply redacting the few that he doesn't want around. That is actually a workable solution, if Yvain agrees, all we need is for this to come to his attention. (And again, if that takes grunt work and effort, I am willing to invest it.)
