This was only for true before svn 1.5 (before it had 'merge tracking'). Also, branching and merging by far wasn't as essential in svn as it is in a decentralized version control system like git. In a centralized version control system it works perfectly well to do all development in the main branch, and only branch off dead-end 'release branches' which are never merged back.

Tbh, I really wonder where the bad reputation of svn is coming from. Git does some things better, especially for 'programmer-centric teams'. But it also does many things worse, especially in projects where the majority of data is large binary files (like in game development) - and it's not like git is any good either when it comes to merging binary data.
