I would say that syntax highlighting, including flagging syntax errors in real time, is not useful enough to me to incur the overhead of linting the code in real-time, these days often requiring a language server. I have my editor set to lint the code on save. Other programmers may find real-time syntax checking useful. Showing possible syntax errors in the code during editing doesn't require full syntax coloring. I understand that syntax coloring can also show syntax errors, but the two features are independent, and you can flag errors without turning the editor window into a kaleidoscope.
