The main problem is giant publication latency. Typically there is at least 6 months delay by the time you submit paper, it gets reviewed and then actually published with proper DOI etc. These days 6 months is loooong time.

I wish there was some way to generate all relevant bib information as soon as paper gets accepted which then can be added on arxiv immediately. This would allow folks to distinguish between peer reviewed papers vs those which are submitted only for flag planting.
