I think they try to unify their rendering workflow, just like chromium did when they forked off blink and switched to skia.

In WebKit, however, that implies that they refactor the Bridge API that is used in between contexts and processes which was an internal API before and broke away often.

So I'd guess they start to do incremental changes on the Web API implementations first before they break too much anywhere else (e.g. sidebars, UIs, widgets, devtools are rendered differently but rely on the very same Bridge API)
