Magento is not officially compatible with PHP 7.2. See http://devdocs.magento.com/guides/v2.1/install-gde/system-requirements-tech.html
I can see you're a moderator so maybe you might know a little more about the development of Magento. My question to Magento developers is, Why till now, even in/with Magento 2, it takes so much server side commands to set up or install and run Magento? Compare to many other CMS' or even eCommerce platforms, they are more like just plug and play when it comes to the platforms themselves. Of course there always more work to do to make platform work or run applications, but Magento 2 itself requires too much work to just set up or install.
@sappoutsource That's a hard one to boil down into a single, comprehensive answer. And one I can only give my opinion on as I don't work for Magento.
Some command line commands are generic to the PHP community which we didn't have for Magento 1 as it wasn't around at the time that was built. Nowadays, it's pretty standard approach to manage dependencies but definitely adds complexity.
Some of the other commands are Magento specific. Many of these are due to Magento wanting to be highly extensible. The ability to have any section of code rewritten by extensions with fewer conflict risks than Magento 1 comes at a usability and ease of development cost.
