Not really. This is the nuance that some people miss: you could only use the IE11 engine inside Edge when an administrator explicitly enabled your website to be there. This has two consequences: a) All ActiveX extensions are dead. This is problematic if the reason why IE is still being used is because it required an ActiveX content to work (so you couldn't just flip the switch to IE11 compat mode in Edge, you need to rewrite it since three years ago) b) if you're developing a public-facing website, you can stop worrying IE11, but if you're developing enterprise software you're still in hell for around seven years (give or take if Microsoft offers an ESU à la Windows 7).
