What does it mean to “avoid a short single word” in quantitative terms (and
across languages)?

Can you confirm that this table means that the “pretty” algorithm is disabled,
rather than the feature listed being disabled in favor of “pretty”? :)
Anticipated spec changes
Open questions about a feature may be a source of future web compat or interop
issues. Please list open issues (e.g. links to known github issues in the
project for the feature specification) whose resolution may introduce web
compat/interop risk (e.g., changing to naming or structure of the API in a
non-backward-compatible way).
None.
I'm also not aware of much in the way of spec changes that would introduce any
compat problems, since the spec gives a *lot* of leeway to the UA for this
feature; so I doubt changes would cause non-compliance.
Instead, the primary thing to analyze would ways in which Chrome's own
interpretation creates compat or interop issues, or locks in browser behavior
or Web-developer expectations that we may want to change later.
So I agree largely agree with Alan Stearns's comments, and in the context of
those comments, I want to ask, if the primary goal is to avoid short last
lines, is “text-wrap: pretty” the right approach, or should we be considering
a proposal that allows more configuration?
For example, there have been in the past a proposals for a property like
last-line-length: <length-percentage>
which is discussed in the issue you linked to:
https://github.com/w3c/csswg-drafts/issues/3473
Note that “text-wrap: pretty” was originally intended to apply better
line-breaking throughout the paragraph, not so much to control the length of
the last line.
