No-one really knows yet. Some educated guesses:

1. The R&D flag will probably remain - but getting root from scratch should be trivial with the new package management. Effectively a simple package could be produced with a setuid shell if root access is blocked as now.
2. The extrootfs using symlinks[1] will need to be re-applied, but it will also need rethinking: /var/lib/install will no longer exist and packages are "intermingled" with the system files. This will make them very tricky to extract
3. There is suspicion that swap will be officially supported due to a line in the new marketing material. This could just be typically confusing marketting, though.

Also, FWIW the forum isn't so big that spamming the same thread all over the place is worthwhile.

HTH,
