In org-roam v2, a new requirement was added for all notes to have an org ID. This has a few notable downsides.

It clutters the note. The preamble alone is a minimum of 4 lines compared to 1 before due to the addition of the
It hurts portability. Previously, org-roam files used to ‘just work’ in Working Copy, including links to other files. It doesn’t anymore because of ID links. It also further locks the implementation in with org-mode which is lacking parsers to make it more ubiquitous (go-org is a good option, but many more are started and abandoned).
