@ilya-biryukov Sorry. I didn't have time to post comments here.
The usecase that we have is a supportive translation unit for code completion. Probably you use something similar in clangd not to wait for the TU to be reparsed after a change?
The gain from this change is both performance and memory but I don't have measurements under my hand right now. And of course they are only valid for this usecase.
