This "seems" like something we could add right now.

BrowserLiveTabContext:
  return sessions::ContentLiveTab::GetForWebContents(
      browser_->tab_strip_model()->GetActiveWebContents());

Our version:
  return sessions::ContentLiveTab::GetForWebContents(
      tab_model_->GetActiveWebContents());

Same general comment as above

Add a comment that Android does not support the concept of pinned tabs.

We should add NOTIMPLEMENTED() in places like this so we can better track it
