I see, thanks for the clarification. If that is so, "Positive signals"
may be better than "In development"? It doesn't seem like anybody is
working on it (yet).

There are some Mozillans who attend our monthly ECMA-402 calls, and
they've signed off on the latest version of Intl.Segmenter. The spec
is written such that it's not necessary to use ICU as the breaking
engine, and IIRC, the intl team at Mozilla got approval to add in the
segmentation data if they decide to go the ICU route.

TAG review
review by ECMA402
Summary
Intl.Segmenter implements methods for finding the location of
boundaries in text, including grapheme, line, word and sentence
boundary analysis.
Motivation
Currently, chrome is shipped with Intl.v8BreakIterator - a non
standard way for similar functionality. According to
https://www.chromestatus.com/metrics/feature/timeline/popularity/556
<https://www.chromestatus.com/metrics/feature/timeline/popularity/556> on
2020 Feb there are 0.74% of the web page use it. Intl.Segmenter
is the web standard to replace it.
Risks
Interoperability and Compatibility
The specification is moved to Stage 3 in TC39 2020-Jul meeting
with support from ECMA402.
/Gecko/: In development
(https://bugzilla.mozilla.org/show_bug.cgi?id=1423593
<https://bugzilla.mozilla.org/show_bug.cgi?id=1423593>)
FWIW, in development seems a bit of a stretch since there hasn't
been activity in the bug for a while.
The patch is three years old and there was a bit of a concern due
to the binary size growing quite a bit
<https://bugzilla.mozilla.org/show_bug.cgi?id=1423593#c9>.
(Not an expert on this, but Gecko's layout engine doesn't use ICU
for line-breaking, IIRC, so a lot of the ICU data that would be
required for this has to be imported).
There may be alternative implementation strategies or what not,
but it doesn't seem to be actively worked on.
/WebKit/: No signal
/Web developers/: No signals
Ergonomics
Engineer from Apple believe we should not add line break support
to the Intl.Segmenter because the developer may abuse the API and
perform text layout by themselves instead of depending on CSS.
The line break feature then were removed from the specification
in the current shape.
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, Chrome OS, Android, and Android
WebView)?
Yes
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_platform_tests.md>?
Yes
