hentry errors

Just wondering why wordpress hasn’t fixed the hentry errors that keep showing up in webmaster tools as I see countless manual fixes that require some html knowledge. Surely the developers will address this issue at some point as it seems to be very common problem for all. I get them and all I am doing is creating posts the standard way no special formatting at all. This tells me that it is a wordpress issue and not mine. I am using default everything, themes etc. I guess I could try and figure it out myself but what happens when the twenty something themes update? Has to be a way to do this without constantly having to go back in and apply the patches again and again. Can anyone shed some light on this? Is there a reliable plugin that does it for us?
