I like the changes you propose here. It also looks to me like you wanted
to wait for Mahi to send the updates herself, which I appreciate.

Mahi's internship ended last week and I believe she told me she's
planning to be very busy this week; so if we don't hear from her by this
time next week, I'll send a reroll with these changes (unless you want
to just take them yourself without the list churn).
