Right, but I doubt that it's for exactly the reason you think it is: Chrome doesn't blindly do "one process per tab" anymore, and hasn't for a bit.

You can enable it (as I have) on chrome://flags/#enable-site-per-process

Strict site isolation Security mode that enables site isolation for all sites. When enabled, each renderer process will contain pages from at most one site, using out-of-process iframes when needed. When enabled, this flag forces the strictest site isolation mode (SitePerProcess). When disabled, the site isolation mode will be determined by enterprise policy or field trial. – Mac, Windows, Linux, Chrome OS, Android
