Magento was one of the biggest pains of my career.

I am obviously exaggerating but Magento might have an xml file to configure another xml file.

It does! (Or it used to.) The global configs defined the cache-specific configs.

edit: Which defined the page-specific caching configs. It's XML all the way down.

I said it as a joke but.. turns out its true. I am still not surprised, Magento cannot surprise me anymore.

Config in M1 was a bit schizophrenic. M2 introduced separated configs by function and (finally) XSD. Tooling is underway so that developers have to spend less time in XML.
