Yes, that's what happens for unspecified versions.

No need to count users with such impression, given such impressions can 
be driven by incorrect assumptions.

For example, it's in no way my job to make an wl-talking app given a 
contraint about programming language to use.

I just do not have much preference about wether or not to include 
wl-support in future apps I probably won't write.

Isn't a collection of common pitfalls exactly what people working on 
making wl better need? It's always difficult to identify why other 
people's workflow is diffrent from your own.

What I can tell about wl now is that I haven't yet identified lines of 
text or code about it, that might probably be of not so much relevance, 
given specific sets of workflows. That's bad news to me, a 
disappointment, because making things easier for the distant future was 
my only motivation for focussing on wl a bit.
