It was never an official Ecma-402 API, it is about to be superseded
by Intl.Segmenter and it's prone to crash under some circumstances.

Searches don't turn up any usage in the wild and the recommendation
from the V8 team is to remove it so now seems like a good a time as
any to do just that.

Does this actually fix #14909, when the property delete is in lib/internal/process.js, so the main context only?

lib/internal/process.js Outdated
'DEP0017');
Object.defineProperty(Intl, 'v8BreakIterator', des);
}
if (typeof Intl !== 'undefined' && Intl.hasOwnProperty('v8BreakIterator'))

Is the hasOwnProperty check necessary?

No. I kept it to keep the logic more or less the same but I'll remove it.

@TimothyGu That did give me an idea on how to approach it more holistically from C++. PTAL!

Lgtm but the text in the deprecations.md section could be updated to not say "will be removed" to "has been removed"... Perhaps with a reference to Intl.Segmenter

Some documentation would be helpful so that reader of the code would not need to look it up in node.cc.

It was never an official Ecma-402 API, it is about to be superseded
by `Intl.Segmenter` and it's prone to crash under some circumstances.

Searches don't turn up any usage in the wild and the recommendation
from the V8 team is to remove it.  Now seems like a good a time as
any to do that.

Updated with suggestions. I also fixed a logic error in the test that was carried over from the old test because I wanted to keep the diff small...

Just a question: has anyone tested that this works on no-Intl builds?

Edit:

addaleax | TimothyGu: so it turns out --without-intl makes nearly all tests fail on master anyway
