It does not make a difference whether a module is static or dynamic.
The code is the same. But in my oppinion development of dynamic
modules is easier as you don't have to recompile nmap everytime you
change something in the module and distribution is of course easier too.

| You're right, stopping other common Lua modules from working is

As long as nmap could still load dynamic modules this is fine with me.
I am not using static nmap builds so I don't mind, but as the RPMs use
~ a static build people using RPMs might think differently.

Cheers,
Sven
