I fully agree with you.
I wish people would stop focusing heavily on how removing features can potentially decrease attacks.
Especially when those exact features are used to prevent the WORST possible attack vector, a mishandled or exploited Clipboard. I do not see how else would a user be able to gain access to the passwords without either using the keyboard, or opening the edit dialogue to select "show password" which would just make them plain-text and MUCH easier to attack.
These features were introduced to not only offer ease of use, but to facilitate a more secure method of transferring the password to the desired location.
These maintainers clearly did NOT think these things through and potentially created a much less secure package than intended.
