Platformio is not simple by any means. That few .ini files generate a whole bunch of python, and this again relies on scons as build system.

That's a nice experience as long as you stay within predefined, simple abstractions that somebody else provided. But it is very much a scripted build system, you just don't see it for trivial cases.

For customizations, let alone a new platform, you will end up writing python scripts, and digging through the 200 pages documentation when things go wrong.
