That's why Microsoft is developing "VFS for Git" https://vfsforgit.org/ to address these issues, so they can use it for the massive Windows code base without being blocked by Git. Compared to that code base and its number of concurrent developers, Squeak and its ancestry are tiny, there should be no problems at all. And yet we argue regularly about saving space and time by folding a few Monticello versions together.

Monticello's abstract design may be nice, but its current approach to storage (which should be an implementation detail) is not. To make things worse, independent from Monticello, "how to store Smalltalk code in a file system" is another efficiency discussion as we can see in the opinions about the Tonel format.

What he says.
