Because KISS is the way to NIH
I wish SASL was more like GSSAPI. Sure, GSSAPI is horribly overengineered, way too generic and too complex but at least that scares people away from going NIH on it.
The fact that everybody has their own SASL implementation is not really a problem by itself, but most of the implementations only cover a few of the wide range of SASL mechanisms (PLAIN and DIGEST-MD5 usually) that are standardized. There's also tiny bugs that spring up because the implementations differ; for example, inserting whitespace between the elements in a DIGEST-MD5 challenge breaks some clients.
