The 2nd half of the article is an explanation of the problem of reading enums referenced in attributes, specifically about how it impedes performance, which I am directly discussing, both in this thread and https://news.ycombinator.com/item?id=48373294

Seems you didn't read the article!

The author is saying the .NET devs did a bad job implementing that, they are not saying you shouldn't use it. So you talking about using attributes is irrelevant to the article, it has nothing to do with developers using attributes nor how they do so.
