Slide to Type languages support

Hello,

It's been a while since Slide to Type has been introduced in iOS 13, which was a long awaited feature for some. Still, it's only been supporting just six languages and no other languages were ever added to this since that time, e.g. Russian which has a major share among iOS devices.

It is both surprising and frustrating to see that this feature has never been updated not only in the minor iOS versions but also in the 14th. From the latest keynote, it seems that the feature won't support other languages in iOS 15 either.

Does it mean that the feature update requires yet another major iOS version, i.e. 16th, or the language libraries can still be included into minor system updates?

Please, just add Russian language (and other) support for Slide to Type, so just the stock iOS keyboard can be used.
