I don't think making a web-based version would make sense for TDF. It would basically have to be done from scratch and OnlyOffice is already years ahead of them in that. Any attempt to port the existing code to the web also seems destined to fail (see Collabora). What I think would really make LO stand out is strong collaboration support in the existing desktop editors. A self-hostable headless sync backend that streams real-time changes from and to everyone who has the document open would be even better than GDocs, which is notoriously slow due to being all in a browser.
