@sanjarcode we'll adjust the docs, this warning is a bit overzealous. There aren't significant implications of adding ref to a particular property. We just advise using ObjectIds for refs for consistency because MongoDB generates ObjectIds for _id by default, so if you prefer numbers or UUID buffers you need to be careful that you're consistently generating numbers or UUIDs for ids. This was more important in older versions of Mongoose before setDefaultsOnInsert was enabled by default.
