Actually, that does not correspond to what the documentation says. 
The way we do things (i.e., modify .templateconf to define a default 
TEMPLATECONF) _is_ what the documentation says one should do. See:
https://docs.yoctoproject.org/dev/singleindex.html#creating-a-custom-template-configuration-directory

Also note that templateconf.cfg is not documented at all. My guess 
(based on the current code) is that it is only supposed to be used 
internally as a way to store the value of a previous build where 
TEMPLATECONF was explicitly set.

So based on the documentation, the officially supported ways to 
configure the template directory is to either specify TEMPLATECONF 
explicitly or by modifying .templateconf to set a default value.

That said, I do agree with your suggested change to prefer an 
explicitly set TEMPLATECONF before a value from templateconf.cfg, 
which also agrees with the idea that templateconf.cfg is only an 
internal way of storing the last TEMPLATECONF used.
