I think there are a lot of people out there who can tell you horror stories
of third-party vendors that for one reason or another do not offer support.
The company may folded, or the support fees is simply outrageous.

Look, if someone is dead set on stealing your code, disassembling is not
going to stop him.

In older versions of SQL Server, SQL Server did in fact stored some sort
of "object code" in sysprocedures. This was abandoned with the re-
architecture in SQL 7. This also resolved some gotchas that came with
the old arrangement and the final result is a cleaner architecture.
