Here are a few more potential downsides not mentioned so far.
One is that iOS and Windows Store policies disallow JIT. While you can
disable this part in LuaJIT, most of the performance advantages
disappear when you do this.
Additionally, if you want/need to modify Lua, it is much easier to
modify canonical Lua as opposed to LuaJIT. It is also easy to find Lua
patches ("power patches").
On a similar vein, I would imagine auditing code for things like
security or high availability would be easier with canonical Lua.
(Look to Wikimedia Commons and Verisign talks about what they needed
to accomplish.) If you or you have users that worry about this kind of
thing, they may be more reassured if you retain compatibility with
