Either no one has noticed much, or they're staying quiet now that this is corrected. Another thing worth noting in 4.1 is that PVSCSI and VMXNET3 are no long limitations to using Fault Tolerance. See the 4.0 availability guide and the 4.1 availbility guide and compare the Fault Tolerance Interoperability sections. I tried to get people to comment on it (Duncan -- I'm looking at you!), but I haven't seen anything. However, Scott Lowe and some other big names (sorry to single you out Scott) all made sure to let everyone know it could cause issues. Very glass half empty, can't do this can't do that, but when something improves the same motivations to make sure everyone knows doesn't exist. I dunno, maybe I'm just cynical.
