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.
It's also a fundamental problem of security research. Lot's of irrelevant, highly contextual "vulnerabilities", submitted to farm internet points (driven by a broken cve system). AI only amplifies this.
Well, some engineer somewhere made the recommendation to go with AWS, even tho it is more expensive than alternatives. That should raise some questions.
