I am looking for confirmation that if you want to update a userprofile, using webservices is still the only way to go.
I have found articles like this:

Let's start by updating the current users (your own) profile, but others (from a XAML workflow wiht elevated rights for example) would even be better !
To be clear, I refering to Sharepoint Online.
