Looks good. Is Truncated the only "wrapper" distribution that needs special treatment? I thinking aboutCensored, maybe?

Truncated is special because it doesn't just operate on the input dist, but does either icdf or rejection sampling, so it doesn't print the name nicely, whereas for Censored you see something like Censored(normal(0, 1), ...)
