As far as I know Japanese, Korean, Chinese, and AGA rules do not allow
suicide. Only SST and New Zeeland rules allow suicide. Whether these
two are to be considered major rulesets is debatable, but from a human
perspective I would probably say no.
afaik ing foundation donates 100,000$ to the us and european go 
organizations every year, so that they promote the ing rules. 
both the european go congress and us congress  use ing rules for the 
main event. and this is the main go event of the year on those continents. 
what more do you need to consider them major? (and should you not in view 
of what you say ask your national organization to stop receiving the ing 
money)?
