To be precise my complains against serpent is only one: we will
need to patch it on top to handle special symbols from "box"
(as mentioned in the original github issue box.NULL). Note that
the seializer I provided are mostly taken from Konstantin's
draft patch (see https://github.com/tarantool/tarantool/issues/3834)
which in turn is derived from
https://github.com/stevedonovan/Penlight/blob/master/lua/pl/pretty.lua
i guess.

I think currently we don't support "block" mode (or as serpent names
it -- multiline output). For simple examples of output serpent provides
same data as our console.fmt code but I think the devil in details which
I didn't discover yet.

Thus if you're _quite_ sure that we better should use serpent then I'll
try to prepare new version and we will see how it looks.
