I'm not super excited on the premise of storing things in the webserver\webapps\main\ directory, for two reasons.
- Our installers delete that directory on upgrade, so you'd need to be mindful about managing those tiles yourself on upgrade
- I'm not an expert on the matter, but my understanding of how files in that directory get served up is sort of a byproduct of some stuff Jetty does. Meaning, nothing we wrote in our code base is directly facilitating that behavior. The next time we upgrade Jetty, that functionality could just disappear.
Point #2 is a big part of the reason why the user manual doesn't really suggest putting things in that directory. I could see using a WebDev Mounted Folder or some other webserver to store the tiles, which the component page you suggested could mention.
