Thanks to Stas & Billy for their suggestions. Here is my current 
workaround. First, I have a program called myprog_svy_check.ado.
program myprog_svy_check
         version 12
         global svyused "svyused"
end

Then, within myprog.ado, I have added this code:

// Make vce(robust) the default if not otherwise specified
if "`vce'`robust'`cluster'$svyused" == "" local vce vce(robust)
macro drop svyused

Hopefully that covers all the possibilities, and does not have any 
unintended consequences. (I could just tell users that they will 
usually want to specify vce(robust), but I would prefer to just set 
the default to what should be the most common choice given the method 
being used).
