It's already a sub-tree of "attic" -- ie out of date, retained for archive.

The title index is useful:

Maybe "attic" isn't the best name. Maybe each page should have a header saying "Historical value only".  But I hate the idea of outright deletion!


PS: I am leaving Microsoft at the end of November 2021, at which point simonpj at will cease to work.  Use simon.peytonjones at instead.  (For now, it just forwards to simonpj at
