Why does only the German (Switzerland) Gboard layout have umlauts? I was looking for a way to add umlaut keys to my German keyboard and found this workaround. I can't imagine why Google did not manage to include them in 7 major versions (I am using 7.1.1). Especially considering that Germany has a population 10 times the size of Switzerland.

Is there a sensible (technical) reason why only the Swiss variation of the German keyboard has keys for the umlauts ä, ü and ö?
As of the latest version (8.0.5), Gboard supports dedicated keys for umlauts on all German keyboards.

However, they will only show on the German variant of the keyboard, instead of the default QWERTZ variant on some locales (e.g. Germany, Austria), excluding the exclusive Swiss variant on the Switzerland locale.
