Changes between Version 3 and Version 4 of Ticket #50448, comment 13

v3	v4
1		Of course we could do it. Just update the buildbots to libc++ - all at once - and instruct the few remaining people using these systems to change over to libc++. No worse than the usual significant upgrade. Once the buildbots are updated to libc++-linked binaries, the upgrade would be fast and essentially effortless. It's just a chore now because of the three-day builds on these older systems (which is why we're even talking about libstdc++ in libgcc in the first place).

3	3	Done. Never look back. They won't go anywhere, I don't think. Homebrew, far as I can tell, has poor support for these systems. And as everyone points out, more and more software requires cxx11+ anyway, so they are going to move to a cxx11-supporting one way or another. Might as well be the right one.
