Yes. If the plugin stays enabled, it replaces some of the core endpoints, so we recommend disabling/uninstalling it in order to use the functionality now in core.
Currently, the following:
| Supported | Examples |
|---|---|
| Main lists | /latest.md, /hot.md, /top.md |
| Personalized lists, requiring authentication | /new.md, /unread.md |
| Default category/subcategory lists | /c/support/6.md, /c/parent/child/12.md |
| Single-tag lists | /tag/example.md, /tag/example/123.md |
/categories.md and /tags.md are additionally supported as directories. Route definitions
I am not too familiar with the Cloudflare feature, but from what I can tell, it catches the Accept text/markdown request before it hits the server, converts the html and then serves that. So, it looks like that feature would override the Discourse one, if/when using Cloudflare.
