A lot of these words strike me as arcane and obscure. Keep them in the OED, mention them in articles like this, but I don't see them having a lot of practical usage.

I do have a special affection for the words fingerpost and mountweazel. I'll often use mountweazel as a sort of easter-egg/test page in my new web projects (e.g. https://sweeperscalendar.com/mountweazel)

I think Cassandra is a more deserving epithet for women nowadays than Xanthippe.

Finally, a few favorite terms of mine somewhat in this vein:

- ramshackle

- crackpot

- dogeared

- touchstone

None of these words are lost but they are expressive and exemplify a kind of poetry that words can sometimes capture.
