option io_server can also be an atom()

(not for dialyzer but human consumption)

Very minor thing: it happened to me that when I quickly looked at the option section of the docs online (http://ferd.github.io/recon/recon_trace.html#type-options) I initially thought that io_server option must be a pid (maybe recon does something special with it). I only later saw that the textual docs clearly state that it also can be an atom and looking at the code also makes this obvious.

Yeah, as long as the atom refers to a registered process, it is allowed.
