More to the point I was making, we can’t use time as an accurate comparison. Because 5e is much slower of a release schedule, EVERYTHING non core is coming out slower. Just because it might take 5 years to release a psion doesn’t mean it’s been any less of a priority than any other edition that took maybe two years. They both could be #25 on the priority list of products for all editions, but those other editions just churned out material much faster.5 years is early days yet, haroom-harum, no need to be hasty.
A much more accurate comparison is to look at how far down the product line each additional feature had come out. Because this tells you how each edition has prioritized the feature.
