For a professional devops person managing a custom backup solution, I agree.
For someone using mainstream consumer technology on a consumer laptop, it's not realistic to expect this. It needs to just work.

Mounting an SMB share on a Synology NAS to use as a Time Machine backup target is not what most users would consider "consumer technology."
I'm not in devops. I don't even have a server aside from the basic usage I get out of my Synology.
However, I have lost data in my lifetime. If you value your backups, check on them.
Also, if you're the kind of person who has a Synology, it means you had to buy a NAS, drives, and setup all the associated machinery for Time Machine over your network. Therefore, I feel it's not outside of the expectation that you can check on your backups. Even if it's just a quick test of a restored file or folders.
