app
with higher precedence

Due to how precedence works when looking up templates, you can write an
app that e.g. in one of its views references a template name in the same
app, but that will never actually be used if one by the same name exists
in another app that is listed earlier in `INSTALLED_APPS`.
This can be quite a surprise and frustration if you are not aware of it,
trying to debug why your template is not being used. The common solution
is to have an additional subdirectory in the app template folder, named
like the app itself. But you will have to find that out first, somehow.
I'd suggest some kind of warning is emitted if an installed app is
referencing a template name that also exists in another installed app with
higher precedence. The warning would ideally only happen if that template
actually exists in the app with lower precedence.
