Problem is, you don’t always get error codes. An error code is only useful, if you can output it to somewhere, so lots of machine manufacturers or programmers save themselves the trouble.
And error codes are an incredibly limiting interface. You can’t provide dynamic information with them. Or, programmers may choose to include an error into another error code, because it’s “close enough” for them to not want to update the manual.
Meanwhile, text logs get all the detailed information you actually need for debugging, with the downside of being an entirely unstable interface.
I’m not happy about this state of the industry either. I’m just saying, many companies will gladly take 95% accuracy over having to upgrade their machines or investing time to ingest the various signals.
