OK, so we have that now. I suppose this spreadsheet now tells us which
places are useful and which aren't, at least for the queries that you've
tested. Dowe that mean that we want to get the patch to consider adding
paths only the places that your spreadsheet says are useful? I'm not
sure what the next steps are for this patch.
I wanted to note here that I haven't abandoned this patch, but ended
up needing to use my extra time for working on a conference talk. That
talk is today, so I'm hoping to be able to catch up on this again
soon.
Good! I'm certainly looking forward to a new patch version.
As discussed in the past, this patch is pretty sensitive (large, touches
planning, ...), so we should try getting most of it in not too late in
the cycle. For example 2019-11 would be nice.
