We could easily do that.  But encouraging users to set a variable called
`default-frame-alist' in a hook is probably a very bad advice.  Where
would you change the default value back after you're done with making
the frame?  In `after-make-frame-functions'?

Creating a frame under the mouse cursor should be done by a special
function that calls `make-frame' with the mouse position passed via the
`left' and `top' PARAMETERS thus _overriding_ any default parameters.
Please tell us if and why such a function would not be practicable for
you.
