Just working through some FB projects in SQL 2012 and found this little nugget, http://msdn.microsoft.com/en-us/library/ms162827.aspx mentioning that SQLMaint.exe is going to disappear.
This feature will be removed in the next version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use SQL Server maintenance plan feature instead. For more information on maintenance plans, see Maintenance Plans.
