Yes, that's intentional.  Under normal circumstances the editor should
behave entirely independently of the input command stream.

} That's not quite as good as zle clear-screen:
} 
} $ asdf^Lclear
} zsh: command not found: asdfclear

This should almost do it:

function clear2 { zle -U $'clear\n'; zle push-line-or-edit }
zle -N clear2
bindkey '^L' clear2

Where that fails is for a multi-line buffer (i.e., you're at the PS2
prompt or deeper).  In that case push-line-or-edit simply moves up to
the PS1 prompt and the "zle -U" input is discarded, so you'll have to
press ^L a second time.

Optional tweak to avoid having "clear" in the shell history:

setopt hist_ignore_space
function clear2 { zle -U $' clear\n'; zle push-line-or-edit }
