Simple opinion : people in those forums are just common users, that tried a lot of things they do not understand, and when things started working, probably credited the wrong solution to the wrong problem.
There COULD be a situation where the motherboard cuts power to the cdrom drive before the rest, as part of its shutdown procedures. That would be different in differnt brands, but could happen.
If you know what you are doing, there shouldn´t be a problem using the "normal" hdd in the optical drive bay. Just configure windows correctly. Also, no reason to keep the disk "as it was" in the second position. If you want the drive there for the added space, format it and use to store data.
That was my first guess but if assuming it to be true then it is unlikely this behavior can be changed by windows(& user if it is hard coded into laptop UEFI firmware).

I do have several LENOVO / IBM laptops with a main hard drive on it's correct configuration and then a 2nd HDD on a bay that replaces the DVD/CD ROM drive.
I didn't observe the described problem at all ...
Of course this may vary from computer to computer, etc ... So no easy way to know for sure if it will work ok with your specific system without testing it first.
I have asus laptop
I found this on another thread:
"Hi, I want to direct all of you people's attention to the problem that optical drive communicates with bios to tell it whether the tray is open or not. If the tray is open , reading from disk is stopped. That is why when you put HDD or SSD into that slot using incompatible solution, BIOS thinks the tray is open and stops read/write. This problem is mentioned on caddy website(I can't find the page right now but I have read it). They say it is why they let you choose brand and models on their website to sell you compatible caddy. They implement some circuit to send the signal that tray is always closed. Probably that is the function of that button on some of the caddy replicas available on aliexpress and ebay."
I searched some more & found out this issue is not exclusive to Asus but almost all brands & from what I found apparently it has to do with presence of a "diagnostic pin" on caddy board which may get connected in a wrong manner causing issue at shutdown. It seems like nowadays caddies comes with a sort of small switch which can be moved to different positions(2 or 3) & depending on your laptop brand there is a specific position which will result in caddy working fine with no issues.
