I am wondering why you find this omission so shocking?  When I ran
into the need for a function like this myself, I just added it in my
own app and moved on:

    function escape(text)
        return (text or ""):gsub("&", "&amp;"):gsub(">","&gt;"):gsub("<","&lt;")

This didn't seem like a serious enough issue to be worth a complaint,
so I don't think I complained.  (I was busy complaining about other
things, probably, anyway.)  I imagine other people might have done
with that.

There are many large sites in Brazil using Publique! which is a CMS
based on the older version of CGILua.  I don't know how widely
"Kepler" is used, but it is definitely possible to build real web
applications on Kepler.  As an example, you might want to check out, which is a Wiki based on Kepler

Kepler doesn't do everything for you in quite the same way as Rails or
Django, but it's size, it does quite a bit.  In particular, the newest
snapshot adds WSAPI and works with LuaRocks, which both are worth a
look.  LuaRocks in particular, makes it easy to manage packages.  In
case of Sputnik, I now also use LuaRocks to install both Sputnik
itself and to later add plugins.  After installing Kepler + LuaRocks
you can use luarocks to install Sputnik ("luarocks install sputnik")
and you can later use it to for instance add a "tickets" plugin which
would add custom behavior to the wiki, allowing you to use it for
bugtracking.  All it takes is typing "luarocks install
sputnik-tickets".  (I don't advocate the tickets plugin as a solution
for bugtracking - it's really just a proof of concept at this point.)
