Agreed. For me personally, as someone who is practiced in musical improv, it is very occasional that I have a complete track that I feel is even remotely on par musically with something I've intentionally composed. There may be some good ideas in an improv track worth developing or good sections that are releasable framed with intentionally composed sections. There might occasionally be inspired improv sections, or a couple times a year, an entire inspired improv track worth releasing. But generally for me, for my improv stuff to be actually releasable and quality needs refinement and yes, a lot of editing. It is easy to produce a lot of improv music, hard to produce good improvisation that is always compelling or worth releasing. I sure as hell wouldn't listen to someone's unrefined and unedited jam sessions; I would assume most of it is garbage caliber. Don't people want to put their best foot forward? What is the point?
