It's actually more than that: to start discussing this seriously,
Someone™ should study the issue and present a design proposal: which
functions currently implemented in process.c and/or in Lisp are
proposed to be replaced or redesigned/rewritten. It is not enough to
say let's use this networking library, because network communications
in Emacs are tightly coupled with process objects and with primitives
that perform background I/O, and also with the filter and sentinel
functions. The best (and perhaps also the only practical) way of
using such a library is as a drop-in replacement for some functions,
but then someone should make concrete proposal regarding what is to be
replaced and how.

Much has happened since 2016; in particular the network code is much
more asynchronous these days on modern platforms. Not sure how that
blog measures against what we have now.
One issue that one must keep in mind when talking about external
libraries is support for non-ASCII characters: such libraries usually
support only the current locale, so if that is not UTF-8, it may mean
restrictions and subtle issues. By contrast, Emacs's own code is
independent of the locale, and completely under control of Lisp
programs and users.
