No. Browser makers should actually innovate more. The problem with "non standard" comes only from the instances where IE does standard behavior in a completely idiosyncratic way or not at all. There are tons of interesting things that are not part of any W3C specs. Of course browser developers should be creative. But they should not, as the IE team does again and again, make a lot of proprietary extensions _instead_ of implementing the standard specs that cover the same functionality.
