Syntax highlighting in a message is really powerful if your message includes a series of diffs.
```diff
- Remove this line
+ Add this line
```
But even if developers are fine with highlighted code snippets inside message, that still leaves the buggy snippet tool which adds newlines when you copy-paste from it, not enumerated, or bulleted lists, no hyperlinks except verbatim, etc. The no hyperlink part is annoying if you have to link a couple or more long urls and placement matters.
Edit: To add to the list, since slack doesn’t use real markdown it is impossible to included backticks in code samples (e.g. `` ` `` is not a thing, and neither is ```` ``` ````).
