I've installed Chromium from the repository and just want to double check so I don't go hunting for something that isn't there: I presume that this in fact is a version designed for mobile phones? It has a different look that the version I use on my Linux laptop. I can imaging that the mobile version has a lighter footprint, and so it's better adapted to Raspberry Pi. So it wouldn't surprise me if this is the mobile version. But inquiring minds...
With best regards,
Pete
