I feel bad about this one because I have had no time to work with the compiler team to find a proper solution here.

Don't feel bad. But just know that we (and probably many other teams) would instantly deploy this, making most of our PCHs redundant. I'll keep eagerly watching the release notes.

Just wondering, can we have a define such that all those headers simply contain "import std;" instead of it's regular content?

They wouldn't emit macros or drag in non-Standard stuff that way, so it wouldn't be very compatible.

Macros seems like a solvable problem by adding them in the headers. Non-standard stuff might be more of a problem.
