I think Eli is asking us for the exact set of obsolete features you'd 
like to remove. Instead of overwhelming us with the whole list of 
features marked obsolete by 23.1 or earlier, how about listing just the 
features marked obsolete in 19.34 or earlier? That should be a small 
list where we can talk about individual items and get a feel for what 
the overall problem looks like.
