These sorts of issues are quickly going away. While it is true they have not been entirely eliminated, there are some architectures rolling out that should eliminate them. There are a couple technology problems various teams are trying to solve. First is that the editing experience has to be local fast. The new Monaco project coming out from Microsoft soon is an adaptation of Atom that is getting to near desktop editing speeds, including aspects related to Content Assist that require processing of large files in near real time. The second is internet connectivity. Increasingly, the editors that are being embedded in the browser will have transient services that can co-locate within the browser, enabling continued editing / saving even while the connection is offline. These technologies, as they mature and the edge cases are ironed out, should work to improve this concern.
