I think you might have misunderstood the recent changelog notes, but there was really no easy way to phrase it (at least not in one line).
What changed in the recent version was the crafting time for the machine itself. Each reverse factory took 20 seconds to craft, which made it take 60 seconds to recycle. (PS. I kinda snuck this into a previous patch note, as I forgot to include it on release, but recycling recipes have been changed to 3x the base recipe time, as opposed to a set time which might be lower or greater than the original recipe)
The assembling machines (which the recyclers are mostly balanced around) only take 0.5 seconds to craft, even for the t3 assembler. The electric furnace (which is also taken into account in balancing for vanilla) similarly only takes 5 seconds to craft. Even structures like the nuclear reactor and oil refinery only take 8 seconds, so 20 was a little absurd.
Of course, your complaint is still valid, just for a different reason lol. During my testing of the 6.1.x version, I had recycling recipes set to 5x the base cost, which felt like... maybe a little overkill?
Thing is, I don't want structures to take infinitely long to recycle, but I also want intermediates to take longer than they took to create in the first place. Hmmm, maybe just setting a minimum recipe time would work... and leaving any recipe times above that as is.
