Well, we can not reach the point not only because we have
different opinions, but because the discussion is so slow.

The reason to store all persistent objects of the same type in the
same space is that Tarantool is designed as a multiple frontend
system. I.e. tomorrow there may be another front end, not just Lua
or SQL, and one doesn't want to have a separate table for each
front end.

If the trigger timing, action type, definer, setuid and other
semantics is the same, and only the language is different, then 
why duplicate the space? Whenever we add a new property common to
all triggers (e.g. persist enabled/disabled), we'll have to do
extra work.
