Have you actually seen this causing excessive load, or is it only a
theoretical issue?

I expect it would be possible, in the case of scan-path, to load repos
from disk lazily, but that will probably add quite a lot of complexity
and I'm not convinced it's worthwhile.

That particular loop will only be executed once and I suspect it is
dwarfed by the time spent loading and parsing the config (cached project
list if you're using scan-path).
