This sounds like deleting the "source" in Firebird. This means
that later users don't get to see the nice formatted and
commented code... but it does not really hide anything of
great importance. Remember: if the server can read it (which
it has to be able to do to execute it) then with open-source
you can soon create a version that will output what it read.
