Forced sending queries to the server without parameters
Queries may be with or without parameters:
where id = :ID
However some database servers execute queries without parameters faster than the same queries with parameters. An option (for example, AllowParams) may be added; if this option is set to False, all queries will be sent to a server as text.

This is more a "parameter by value" replacement feature.
It may lead in sql injections.
Also different DBMSes handle parameters in different way. Quoted/unquoted, date format, etc...
This is a SDAC only suggestion in my opinion
This feature is very important because the queries with "exec sp_executesql" are very slow. As with plain text is very fast.
