Twitter 上看到「PHP RFC: Unbundle ext/xmlrpc」這則消息，PHP 官方打算把 XML-RPC (也就是 git repository 裡面的 ext/xmlrpc) 拆出去，移到 PECL：
Unbundle ext/xmlrpc (i.e. move it to PECL) without any explicit deprecation.
主要的考慮是在於目前的 library 已經年久失修：
ext/xmlrpc relies on on libxmlrpc-epi, which is abandoned. Even worse, we are bundling a modified 0.51, while the latest version is 0.54.1. This is exacerbated by the fact that the system library is usually built against libexpat, but the bundled library is likely to be built against libxml2 using our compatibility layer.
另外應該也是因為 XML-RPC 用的人不多吧，投票是沒什麼玄念的 50:0，而且在 Packagist 上面也可以翻到一些用 PHP 實做的替代品，拿 xmlrpc 這個關鍵字搜了一下可以看到一些...
