Make still does this. (That's the "Stop." in the famous "* missing separator. Stop.") Many errors in Python still do this.

As late as 2010 I still saw some major C compilers do this.

99% of the toy compilers written for DSLs do this, or worse.

Good error recovery / line blaming is still an active field of development.

True. But let's get terminology straight: that's not a compiler science, that's parsing science. And it's no more compiler science than parsing a natural language is.

What terminology are you talking about? Neither "compiler science" nor "parsing science" are terms I used, or that the industry or academia use.

Parsing - formal theory like taxonomies of grammars, and practical concerns like speed and error recovery - remain a core part of compiler design both inside and outside of academia.
