I agree that site-specific solutions are superior (if they are actually implemented). I agree that considering this, my original post was quite off-topic. Fortunately, my original off-topic thread about a proposed general solution was hijacked into an on-topic conversation about the best LW-specific solution. I think satt and Misha gave a quite acceptable temporary solution that would deserve some more visibility. Meanwhile, HonoreDB implemented my proposal (big thanks, HonoreDB!). So everything turned out fine.
