Summary
Links to configurations included with each release lead to latest configuration files only.
Config files are not versioned.

For example, I'm trying to setup cardano-node 8.9.4 pre-prod, I'm not able to get node config file for 8.9.4.
Config page: https://book.play.dev.cardano.org/env-preprod.html
Link to config file on the page: https://book.play.dev.cardano.org/environments/preprod/config.json

Config file says "MinNodeVersion": "8.12.0",.
I don't know if editing this key is safe.
Maybe the 8.9.4 and 8.12.0 config files differ in some other places/keys too.

(This is in addition to missing Conway genesis #5891)

Recommendation
Supply versioned configs URLs.

I was able to run the cardano-node-8.9.4 despite the "MinNodeVersion": "8.12.0" in config.json
But i had to change the "threshold" field of the conway genesis to "quorum" and change the hash in config file as well.

$ cardano-node --version
cardano-node 8.9.4 - linux-x86_64 - ghc-8.10
git rev 8ac5f75342fe3fec14ee410c4c73fd5e2381bb18
