But in case of a read-only buffer, one may want the normal eldoc to show
arglist. So there is two use cases: one when editing and the other when
reading others code. I only enable eldoc-mode manually i.e. M-x
eldoc-mode when I need it.

But then when you go anywhere that you don't want to edit code (such as
just to copy some text) eldoc also prints the arglist. The latter
happens more often in my editing habit that it can be annoying.

But maybe eldoc-post-insert-mode (maybe even a new name
eldoc-edit-mode?) can check on char changes instead? Is this better?

For example, if a heavy job is running in the inferior octave buffer,
one normally don't want any movement to send a request to it asking for
arglist. It is my impression that eldoc might do that.
