Having built my own custom Chromium for Android several times on a project, 250MB is out of line for stock Chromium. My builds for my custom browser with Chromium content-shell were ~70-80MB. Chrome, indeed, adds a bit of extra "google chrome", and probably some additional internationalization, but 250MB does not seem square, in my experience.
