Why does universal autofill not work everywhere?

I am not the OP.

However, I've been having trouble understanding and using universal autofill with terminal apps. I just tried autofill in iterm2 at a sudo prompt. It worked as expected.

I usually use a different terminal app. Either kitty or alacritty. Both of which are much better terminals for me personally. UA will not fill in either of those terminal programs using the command-\ key. Copy and paste works of course.

As I said in my other thread about this, I'm quite confused by this design decision to limit UA to only certain things. I think UA should be trying to help me in any place where I want to fill username, password, or both.

Please consider this a request to allow Universal Autofill to work everywhere, regardless of the application, state of application, or place in the application. Having 1password determine whether or not it will fill is confusing for the end user. When you press the hot key and nothing happens you wonder if you pressed the key. Or if your setup steps were correct. Or if 1password stopped working. Or if the program is buggy. No feedback, failing to do what it is supposed to do, and making its own decisions are all poor behaviors for the end user.

It would be wonderful if it simply filled everywhere. With the possible addition of two autofill modes: Fill username and password, or just fill password.
