I might be missing something, shouldn't the IDEs be encouraged to use
libgit2 instead? I thought it was meant for these use cases.

Note: I assume getting the status through libgit2 doesn't create an 
index.lock file.

So, if I get that correctly "git status --no-optional-locks" is a way
to get the "current" status without updating the on disk index file?

The above sentence seems to be a little hard to interpret. How about,

    If set to `0`, Git will complete the requested operation without
    performing the optional sub-operations that require taking a lock.
