Yes, thats right. And there is another gotcha:

The TYPO3 extensions on composer.typo3.org expect to be installed by one 
of the typo3/cms-composer-installers. If you 'replace' the installer, 
without providing your own implementation and add a TYPO3 extension as a 
requirement, you will end up with: "Unknown downloader type: t3x".

Example composer.php:
{
	"repositories": [
		{
			"type": "composer",
			"url": "http://composer.typo3.org/"
		}
	],
	"require": {
		"typo3/cms": "^7.3",
		"typo3-ter/news": "*"
	},
	"replace": {
		"typo3/cms-composer-installers":"*"
	}
}


To my eyes, there a two ways to avoid this:
* Use git repositories to source the extensions, instead of the 
typo3.org composer repository.

* Provide your own implementation of cms-composer-installers. You could 
download them to ./vendor/$vendorname/$extensionkey and add a symlink 
from typo3conf/ext, so TYPO3 CMS will find them.

It's my understanding that people in or close to the core team are 
working on these issues.
