I do not think this is true.
Setting the temp directory through environment var is not the same as setting it through tempdirectory config value.
The only requirement should be to allow php to write in the directory.

@CaptainSifff Can you explain this change?

I tried setting the tempdirectory and expected this to be usable by nextcloud. As I found out the hard way, there are more prerequisites like the environment variables of PHP or the configuration of PHP. And beyond that there's apparmor and SELinux. And I wanted to point users to this so that they also check this.

But it is not the same thing, if you set the env var you do not need to set tempdirectory config option from what I understand.

I think I had to do both, as far as I recall.
