I can at least name two bugs. both bugs do not apply to everybody and one is fixable with some additional code. I reported both in preview9, one should be included into 3.0 but was not. the other will be fixed in 3.1:

- https://github.com/aspnet/AspNetCore/issues/13696 - https://github.com/aspnet/AspNetCore/issues/13715
