I can’t exactly tell if we’re saying the same thing but my thought was a flag to switch between the 1.2 way for faster startup and the earlier approach for longer running processes. The trade off is added complexity in identifying your binary usage patterns and keeping both methods in the tooling.

These kind of changes may not be breaking in a technical sense but it’s very unexpected behavior if you’re one to notice patterns like file sizes changing in such a significant way over time. An answer of “stick with v1.1x indefinitely if you want the old behavior” only feels like a very temporary answer.

That was my question but I would imagine the problem is then that you can't debug production. It looks like a more common solution is dSYM, .dbg, .pdb or other things (read from another commenter)
