A little twist of logic

As I understand it, the reason the 16HP class does not want a hooter, is it is not competitive under Texel handicap.

You gave some examples using the Tornado. Interestingly there is nothing explicit in the Tornado rules to prevent me from using a "roller furling spinnaker" on a class legal Tornado. The spinnaker launcher is open and the mid girth is "shall not exceed".

What happens if I bring a class legal Tornado with a roller furling spinnaker to a Texel handicap event? Do they give me the standard Int Tornado handicap?

I do not know how Texel is administered in Europe. In the US I am pretty sure I could win an Appeal. My suggestion is take out the minimum mid girth and let any individual who wants to "go for it".
