awesome ask. makes sense.
Impossible to use Windows 10 Servicing when multi-language is used (and this is the case outside US ;-)
That's why I must use Task Sequence to :
1) Switch in US (Default OS language)
2) Run upgrade
3) install New multi language version
4) Install some others stuffs
That's why it could be a really good idea if we could run a TS before & after the Windows 10 Servicing .... or intregrate on it all this functions.

This is actually the most problematic issue we have during the differents scenarios we could encounter with inplace upgrade & MUI.
we have a TS to upgrade Windows 8.1 To Win 10 CB and another to upgrade Win 8.1 To LTSB.
Our 8.1 is be default in EN-US and we apply 3 languages (MUI).
During the inplace upgrade process, I should manage some steps inside the task sequence in a way to switch the 8.1 OS language in EN-US if I want my TS to work well.
I must have multiple reboot (registry change & Powershell script) to be sure that this os Language switch is ok.
During this phase & reboot, the winlogon is accessible and even if I have customized the background wallpaper (with a big warning for users which say, STOP your computer is under upgrade) ... this is not a really nice process.
And I have the same problem with an inplace upgrade for two Windows 10 versions.
This could be really nice if this switch could be managed directly by a "by design" step in Task Sequence.
