IMO the asset pipeline is not worth the complexity.  CDNs + caching do a good enough job of getting stuff to clients, so the complexity (and distinction between dev mode and production mode) isn&#x27;t worth it.<p>My problem with routing is that the default is an implicit semi-REST pattern, and that routing a lot of verbs to the same controller method is tedious.  I prefer Sinatra&#x27;s &quot;ground up&quot; model instead, although you can certainly write a rails router that way (and sinatra has the same verb problem.)<p>But I concede that&#x27;s a matter of taste.
