Out of curiosity, why is the period the separator character for hierarchical columns? I would expect either back or forward-slash.

slashes mean FOLDER on many OS
IIRC it was only 8.3 (DOS) file naming that only allowed 1 period.
+ means concatenation, so that was out

Considering that a) the folder structure is meant as a black box and b) most (or all) punctuation gets normalized to _ anyways, not sure how that would factor in?

You are correct for INSIDE the Library. But what about Send To .... ?
I am not sure if it was Charles or Kovid that came up with the dot

Just a guess: periods are used in a lot of programming languages (including Python) to indicate properties and methods of objects, which can themselves be objects, allowing nested objects of any number of levels. As a programmer, I find a period-separated hierarchy feels natural. No doubt Kovid does too.

Dots are less intrusive than Slashes and Sloshes

Many excellent reasons have been posted, for me it was that slashes exist in tags already for example, SciFi/Fantasy is a common tag. Periods are less common in tags from general metadata sources.
