Are there any implementations of these R&D papers in popular compilers
(apart of Visual Studio, which is obviously not interesting in this
context)?

Isn't it true that all the packages that use clang for completion save
the buffer whenever completion is required?  At least the one I tried
did just that, which sounds an awful design decision to me.  Since
when do we let a feature decide for the user when to save the buffer
she is editing?
