So, what is the actual final verdict on interiorproxies.meta use?

There’s no ‘final verdict’ as long as the weird bug reported in another topic doesn’t have reproduction steps.

This is already being discussed in Need help with MLO's, People disappearing and reappearing - #25 by d-bubble, making a new topic asking for some ‘end all be all of a fact’ is useless and dismissive of the whole underlying point here.
