I think this would be ok.

I think most people have mapfiles for rendering, and while I'm sure 
there are a bunch being used for queries, and it would be a pain to 
change them, this is a onetime event to make the change and we are 
probably going to make them change other things also, like 

I have a lot of 2-5K line mapfiles that I will have to update.

It might be possible to write a perl script to make some or most of the 
changes. Like find all TEMPLATE lines and add QUERYABLE TRUE after it.

Anyway its a thought.
