I think it's inexperience speaking, which is also why it's very dogmatic. If you've seen how standards develop, they're usually taking many ideas like this that have become popular and tweaking the specs to smooth out the differences. The POSIX API is often called Berkley Sockets because a vendor, BSD, released their API and it was widely adopted. ANSI C cobbled together existing C compilers into a standard, and POSIX itself was trying to tame a huge mess of Unices. And even if the standards don't fully converge, you have standard libraries to plaster over the differences. Everyone has to contend with weird Windows path conventions and such, to the point where it's hardly even notable.
