Well eldoc mode remains on it simply won't do the automatic check
anymore when hovering over a function, you can still request the
documenation though the keybinding.

And yes the threshhold can be different for different people if that is
an option that you think would be good to add its pretty simple to add.

The problem with simply returning instead of canceling the behavior for
the buffer is that a second (or so) later eldoc will once again try to
fetch the documentation and will be frozen until the timeout. This means
that you will be repeatidly be getting frozen as you type. It won't be
a complete freeze that crashes emacs but it won't be pleasant.

We're not turning it off but yes a warning would definitely be nice.

Thanks for hearing me out
