The only way it would have "benefited" would be that the web would only be developed by lisp programmers.
To the vast majority of programmers, syntax matters. C-style with brackets, or python whitespace, or Ruby do/end, these fit better the brains of the majority of programmers. Perhaps not the majority of HN readers but the majority of corporate devs.
Another example of this is Erlang and Elixir. Elixir adds a couple of features over Erlang, macros and protocols, but Erlang does everything else. What made Elixir take off where Erlang didn't, after decades, is that Elixir has a syntax that people are comfortable with. Erlang has a syntax that will summon Cthulu.
