I need to preface this by saying that I have the utmost respect for all contributors to org-roam (especially @jethro) and am thankful to all of those investing time and effort into this community.
After yet another afternoon of trying to get v2 to work for me, I just rolled back all changes. While the specific reasons vary between my attempts and are something for a different post (this time: stability, design & functions of the new roam buffer, the design of org-roam-graph, incompatibilities with org-add-link-type etc), here I wanted to pose a different set of questions:
What are the long term negative consequences of staying on v1? Or, in order to give this a more positive spin, what are killer features of v2 that should motivate people like me to migrate? I really like the side-buffer design of v1, do not (intend to) use nodes and am sceptical about filetags.
I have just short of 1800 notes and V1 works flawlessly for me. It has been the main reason I explored Emacs and continue to do so.
