The cache just prevents re-reading a directory content. Do you have a
scenario in mind of a possible problem ?
The only problem I can see is when a project is uninstalled by a
program while these APIs are used by another program.
I guess the problem only occurs if "egg_infos" is part of the public
interface. What if module A calls get_egg_infos(), then module B calls
get_egg_infos(somePath), then module A uses "egg_infos" assuming that
it still refers to the same set of paths.
There's also the issue of API complexity. The global functions don't
add a lot to using an EggInfoDirectories object when you are working
with a different set of paths than sys.path.
