Ok, I accept that it is more effort then I thought. Sorry for that.
But personally I do not accept that blanket answer that there are no good reasons for updating to specific versions. I mentioned a few and they are valid in practice. Searching this forum brings up examples for PiHole (How to install a specific Pi-Hole version · Issue #3435 · pi-hole/pi-hole · GitHub, How do I revert to a previous version of Pi-hole?). But it is ok. Let's say we have here a discussion state of disagreement 
Then let's see if the community upvotes this feature, because that is what a public listet FR is for, isn't it?
