This is an interesting comment because Microsoft is right now in the
process of taking the big fat .Net Framework (that I happen to love)
and breaking it down into a .Net Core platform with "extensions" that
can be retrieved in binary format via Nuget package manager. Sound

This is my position right now as well. I just wanted some client
websocket functionality in 5.3. I have found four different libraries,
and only one of them "meets" my "requirements" (i.e. smell test) and
it doesn't build for 5.3 right now! But should websockets be part of
the base library? I don't think so because the reason I am using Lua
is it's so damn small and fast and light. A more experienced open
source developer said to me that Lua (like his favorite JimTickle)
applications become more dependent on the supporting libraries than
the core libraries. Clairvoyant!
I don't think this is a Lua issue. It's an open source issue. LuaRocks
go and Github go a long way to making other packages more manageable,
but the same problems exist everywhere. Getting more people to write
the code YOU want is hard! There is no one size fits all in software
so the only "practical" answer is to have a small core and build out
your tool chain accordingly. Don't think that MS is changing their
framework out of altruism...
Anyway, I'll be futzing with lua-websockets if anyone needs me. ;)
