+ <entry>if you are reading this prepatorily, please redesign your query to use temporary tables or arrays</entry>
I agree with the documentation of this parameter. I agree with dissuading anyone from attempting to change it The wording is bordering on snark (however well deserved) and I think the voice is slightly off.
Alternate suggestion:
Queries approaching this limit usually can be refactored to use arrays or temporary tables, thus reducing parameter overhead.
The bit about parameter overhead appeals to the reader's desire for performance, rather than just focusing on "you shouldn't want this".
