...this is somehow an extension to this post.

- New C++ sources indexer mode - previoualy, after each file change, all depended files were reindexed. That often resulted in very heavy CPU load after each header change. In the new mode, only the changed file is being reindexed - while less accurate, real problems in this new mode are actually rare and it makes for much more responsive experience using theide.

I think i see your point here, altough the thing is far from perfect(checked both included clang on w7 and msbt17 and no go).
But i think you forgot to see both point of view:
* from developing upp point of view it's probably better(since new mode recompiles "needed" - mostly developing "system" header sources faster),
* from consumer point of view(just using the ide out of the box for a quick project) - original is magic - it works!

With this i incline that original and new modes of indexer should be selectable in Settings,

original mode is a must for people who want: "do it's thing at opening project and then just use it",
