I am super happy with the creation of all the 'latest' links. This makes life very easy for all of us who have to maintain builds and target platform definitions. Thank you!! It is great.
We always also have a target platform for the upcoming release (to make sure that we are still fine using internal and deprecated API 
For platform, we can use /I-Builds and this is, of course, fine but all repos have their specific "next" endpoint e.g. snapshot, nightly, ibuilds, etc..
How about creating a 'next' alias best practice?
