Summary

Remove Element.scrollByLines() and Element.scrollByPages().

Motivation

These were added in 2004 as "extension for Safari RSS":

http://trac.webkit.org/changeset/7901

Miraculously, they don't seem to have found their way onto the Web at large, and are not implemented in any other engine AFAICT.

Compatibility Risk

Content depending on these would stop scrolling and start throwing exceptions. Fortunately, such content is too uncommon to register on the use counter radar.

Alternative implementation suggestion for web developers

Increment/decrement element.scrollTop by some appropriate amount.

Usage information from UseCounter

http://www.chromestatus.com/metrics/feature/timeline/popularity/390

http://www.chromestatus.com/metrics/feature/timeline/popularity/391

Available since M38, and neither has had a non-zero value yet.

Entry on chromestatus.com, crbug.com, or MDN

None.

Requesting approval to remove too?

Yes.

[Philip Jägenstedt]

Correction: the use counters are available since M36, which has reached stable.

SGTM, These can be added back in the future with options in the scrollTop dictionary instead I suspect.

[Tab Atkins Jr.]

LGTM as well, same reason as Elliott.
