I doubt the Unicode sentence segmentation algorithm is so slow.

Do you have examples of NLP-based features that:

    1. People want to implement in browsers today.
    2. Would depend on phrase detection.
    3. Would need to happen *during* page load, rather than shortly
after or on demand.
    4. Where the additional cost of calculating phrase boundaries
would slow page load down so much that the effect on page load would
inhibit adding the feature.

I think we've got a better chance of making client sentence/phrase
detection good and fast enough for clients to use than of getting
sufficient authoring tools to generate such markup that it's worth
browsers relying on sentence/phrase markup in the web corpus.

I'm not sure what you mean by "[w]hile" here. Do you agree that <span>
already addresses these usages or not?

That's more like a rephrase than an elaboration. Are you just talking
about avoiding line breaks within phrases so that readers see (and
quickly recognize) the phrase as a whole, or are there additional
examples of phrase-based text formatting? Do Unicode spaces and
non-breaking spaces address this? If not, why not?

This doesn't sound like it would make for a coherent user experience
on the basis of <phrase> …
