It just needed to be mandated from the EU in the late 2000s (i don't want to bother looking for the article again.)

No it didn’t. If they had mandated it back then, it wouldn’t have been USB-C and we’d now be stuck with and obsolete standard. This is precisely why state intervention is bad.

For the historic context, micro USB wasn't mandated by the EU back then (2009). It was an MoU submitted by the mobile phone industry after the EU started thinking about a standard charging port: https://ec.europa.eu/commission/presscorner/detail/en/IP_09_1049.

However, I don't think that's relevant - the point was that these are examples of problems that don't result in mass complaints, so the lack of complaints can't be taken as an indicator of no issues.

You keep missing the point. If the tests are not robust enough then even a "matched pair" of phone and charger could cause an issue if the issue does not present itself during testing. If it is as bad as say a phone screen going haywire with a certain charger then someone did not do it right in validation. It's like saying that you cannot buy a lap top power supply unless it is the same supply that was tested with the same laptop.

None of the cheap power bricks are tested.
Maybe some branded (Apple, Lenovo, Dell) might be, but still, they are commonly "optimized" after that point
Plus you have plenty of counterfeited ones and you have no idea until you open them
You can buy a charger that looks almost or even exactly the same as the original and find a life threatening mess inside.
And almost every generic one is something crazy, what cannot pass not just EMC but basic safety rules

Yep, yep, yep.

And for someone who claims being so good at EMC that all their devices pass without a single issue, I found their answer a bit odd.
