Intent to Deprecate: -webkit-font-size-delta

[김현준]

Summary

Remove '-webkit-font-size-delta' from web author's interface, and replace it with '-internal-font-size-delta', because we need this internally in blink's editing module.

Motivation

As mentioned in https://bugs.chromium.org/p/chromium/issues/detail?id=974092, the usage of the feature is very low. (0.007%)

Interoperability and Compatibility Risk

Edge: Not supported

Firefox: Not supported

Safari: Supported

Alternative implementation suggestion for web developers

Use the 'font-size' feature, because '-webkit-font-size-delta' is currently being overridden if 'font-size' is specified.

Usage information from UseCounter

The usage is estimated as 0.007% https://chromestatus.com/metrics/css/timeline/popularity/241  

Entry on the feature dashboard

I am not sure if this needs an entry in the feature dashboard, but it may not because of its low usage.

I'm not sure I understand. Would the `-internal` one be web exposed? Or would it only work internally?

That's non-negligible usage...

What would breakage look like? Would the page still be usable to end users, only with a slightly different look and feel?

Deprecations require status entries. That was buried in instructions before. It's explicit in the new UI.

Hi all,

Just wanted to chime in here and say this should be a very safe removal.

This property only has an effect internally within editing (and likely shouldn't have been exposed to the web).

Using an -internal- property instead won't be exposed to the web.

Thanks,

Ian

LGTM1 then, with the comment that you should update the summary at chromestatus to clarify that the -internal version is not web-exposed and is only part of the implementation. (Actually, it might be better to just leave that off since it's not relevant to web developers and might only serve to create confusion.)

LGTM2 to remove, given the fact that breakage is not awful (different size fonts), usage is low and likely to be a loose upperbound, and the fact that this is used in ways we're not sure are correct.
