as opposed to what though?

something like "webview_browser" for things that are webview-specific? safe browsing and spell checking don't sound webview-specific though. where are they registered for chrome?

In Chrome, spellcheck is registered under chrome_service (which is correct), but safebrowsing is registered under content_browser (which is a hack).

For more background, see @yzshen's comment in crrev.com/c/846370

"Because both spellcheck and safebrowsing are chrome-level (or more accurately, embedder-level) concepts, instead of content-level concepts. Content doesn't know anything about them. So it is layer violation to register those features under "content_browser".

I am fine with this as a short-term solution (well, I was the one who registered safebrowsing under content_browser :P). But eventually we should put them in the right service."

 xiaochengh@ Is this a task you should own?

cmasso@: I don't think so. I don't work on Mojo or servicification, and don't have enough knowledge about them.

I'm mostly copy-pasting the issue yzshen@ identified.

Based on the discussion in chromium-mojo, we are still adding new features to content overlay. https://groups.google.com/a/chromium.org/d/msg/chromium-mojo/G2lZfJKP4Kw/xp0t2apxDwAJ

Assign to myself as I experimented adding WebView service http://crrev/c/1398822

Removing yzshen@, since they are not working on Chromium anymore.

content_browser provides a lot of things that webview implicitly still uses via content_renderer. I assume you mean introducing a separate service for WebView-only features in addition to contnent_browser, rather than stopping use of content_browser altogether. Right?

Re #10, yes, this issue is for tracking add a separate service for WebView-only features.

yzshen@'s point was since SafeBrowsing and SpellCheck are embedder level concepts, they shouldn't go with content service, instead we should have a embedder level service as Chrome do to host these features.

Issue 918065 is purely WebView only feature, if we use the same judgement, it should go with WebView service too.
