It actually is a big deal. It breaks the buildcache, which is more important most of the time, and adds a ton of complexity.

To do this right, we would need an incremental task that does .svg -> .tar, 1:1, where the tar would have each file's path and content in some temp dir. Then a separate non-cached, non-incremental task which untars each of those to the destination directory.

More complexity than it's worth, I think.

For now, I'm just ripping out the incremental part, which makes everything else much simpler anyway.
