Can grub2 password request be configured to provide visual keystroke feedback?

[Jimmie Mayfield]

(For the record, I'm using grub 2.0.6 on an OpenSUSE Leap 15.4 
installation...)

For reasons I don't understand, since upgrading to a Thinkpad P50 I have 
a lot of difficulty entering a grub password unless I type very, very 
slowly or wait some amount of time before I begin typing.  It smells 
like the Thinkpad drops keystrokes during early boot though I have no 
proof.  Since grub password prompt doesn't provide any visual feedback 
and since it gives only one password attempt before dropping to the 
rescue shell, booting this laptop is extraordinarily tedious.

Is there an existing mechanism to tell grub to provide visual feedback 
(a hashmark, a spinner that advances on each keystroke, etc) when a 
password is being entered?  I realize would reduce grub's security 
posture somewhat if enabled but one could argue that typing a passphrase 
slower than necessary is even worse.

Thanks for any insights.
