Is mundane jhana needed to attain nibbana?

I’m still struggling with the concept of a sukkhavipassaka arahant. One of my first posts on this forum was actually about this topic:

What do the Commentaries say about jhāna attainment during the decline of the Sāsana? Does the number of non-noble jhāna attainers also decline? Is there such a thing as a sukkhavipassaka anāgāmi?

Do non-noble people find it easier to attain jhāna? Or is it just that noble ones never attain micchā samādhi (wrong concentration)?
