IMHO DT aliases are not a proper solution for this.
Yes, you can detect reliably if an alias exists in the DT.
The problems start when having multiple devices, some with aliases,
some without. And when devices can appear dynamically (without
aliases, as there is no support for dynamically updating the aliases
list).
