Can we make this a metapackage?

Having this as a meta package helps keep the composer.json file clean and clutter-free.

"magento/module-sample-data": "^100.4"

vs

"magento/module-bundle-sample-data": "100.4.*",
"magento/module-catalog-rule-sample-data": "100.4.*",
"magento/module-catalog-sample-data": "100.4.*",

"magento/module-wishlist-sample-data": "100.4.*",
"magento/sample-data-media": "100.4.*"

And also publish this under repo.magento.com? So that we can directly do a composer require magento/module-sample-data instead of running the bin/magento sampledata:deploy command.
