Summary

Deprecate SVGSVGElement.viewport attribute.

 

Motivation

The implementation is trivial but entirely useless and has been since

2012. The attribute is not present at all in Gecko.

 

It has been removed from the spec:

https://github.com/w3c/svgwg/commit/99a342c09dc0f8f164667d45d1c8486f0f87af8f

 

Compatibility Risk

Blink always return empty rect and The attribute is not present at all in Gecko.

 

Alternative implementation suggestion for web developers

None

Requesting approval to remove too?

No. The plan is to show deprecation message and do removal in M56.

The use-counter numbers are recently less than 0.02%. LGTM1 to deprecate in M54 and remove in M55.

Gentle Ping!!!

An "Intent to Deprecate" thread actually doesn't need any LGTM, but since you indicated removal in M56 I treated it as an "Intent to Deprecate and Remove". API owners, one more?

Kent,

Just to clarify:

• Deprecation in M54.
• Removal in M55.

Is this correct?

If an API's not documented it doesn't exist.
