There is at least a non-negligible minority (or a silent majority?) of those who would retroactively call it an improvement if your wish were granted by some magic measure.

Even though I do think decoherence-based MWI is a better model than Copenhagen non-interpretation, it doesn't look like there are any new arguments in support or against it on LW anyway.

But given that LW is run mostly by SingInst people, and they do believe in possibility of FOOM, there is no reason for FAI to become offtopic on LW. Most of the time it is easy to recognize by the thread caption, so it is easy for us to participate only in those discussions that are interesting to us.
