This is because I'd like to keep core.* from growing too big (it's
already big), hard to read, search and maintain. Perhaps this should
belong to a separate group? Something like tuning.something or
defaults.something.

Then instead of numeric values, maybe the user should write some sort
description about the repo and we optimize for that, similar to gcc
-Os optimized for size, -Ofast for compiler speed (-O<n> is all about
execution speed).

We could write, for example, tuning.commitHistory = {small, medium,
large} and tuning.worktree = {small, large, medium} and maybe
tuning.refSize and use that to optimize. We can still have different
optimization levels (probably just "none", "recommended" vs
"aggressive" where agressive enables most new stuff),
