We avoid top-posting replies here.

I’d probably go with adding truncate_start and truncate_end (or maybe just
start…) events for event triggers if we don’t want to include them under
DDL events. I’d be strongly disinclined to touch regular triggers to
accommodate whatever use case you have that would benefit from this
capability. Stating what that is helps to get agreement, or just spending
time helping, making such changes.
