 Well, basically the uClibc configs we have are just a configuration that was
created many many years ago. Occasionally some option is added when there are
important packages that need it, but it's not as if really a lot of thought goes
into these configs nowadays.

 Since you're doing active development with uClibc, I expect that there are some
options that you encounter that actually improve the quality of the resulting
library, it would be good to get patches that enable them (of course with
sufficient explanation _why_ it's a good idea to enable it).

 Your commit 826f315d is a great example of this.
