When display such custom cursor,
you need to do a lot of extra things when you need readline from keyboard.

Nope.
To handle "proper" readline, you need to check for backspace, insert / overwrite, arrow keys, some other keys such as ctrl / alt + keys...

After re-read the 1st post, realized this was talking about waiting cursor in console.
Not for 'waiting command cursor'

If we look at recent common application, including web, desktop gui and console app,
The waiting cursor could be progress bar,
or some text info such as xx mb/sec, xx sec / min reminding, 1 of 999 steps / processes, ...

This may give user some info for them to decide if they are willing to wait until complete or terminate it.

Animation cursor may be is OK for short waiting, but not for long waiting time.
