I have the feeling I'm missing some context on tree roto ids. Iirc
tailor generates file-ids on every tailorization, which makes merging
between two otherwise the same bzr branches made with tailor harder.

Would tree root ids have a similar impact? If each 'bzr branch'
invocation makes a new id it won't, but now I'm again uncertain I
understand what root ids are supposed to solve.
