Is it possible to use the RPC's Label feature in it's current state over the deprecated Accounts feature? I'm doing my bachelor project in web development using Bitcoin RPC. At the moment it uses the deprecated accounts feature, but i'd really like to upgrade to using the newer label feature instead. However is it currently useable on the master branch, or should i wait until v0.17 is fully released? (this is unfortunately after my hand-in date), so if that's the case, i guess i have to stick to using accounts?

Yes, you can use the current Labels function as it is now.
