Ah, I had expected to see no-grab there.

testit at argenau:~$ rm -f  ~/.gnupg/gpg-agent.conf ; gpgconf  --list-options gpg-agent | grep grab
grab:8:2:let PIN-Entry grab keyboard and mouse:0:0::::

I get the same outcome on both Debian/stable (2.2.x) and unstable (2.4.x).

And indeed I get the expected grab/no-grab behavior (on Debian/testing
with 2.4 from unstable). This is with pinentry-gtk2. With
pinentry-gnome3 grab/no-grab is ignored and always enforced, but that is
known completely different issue https://dev.gnupg.org/T4587 ,
pinentry-qt also seems to ignore grab/no-grab but never grabs for me.
Perhaps that would be different when using KDE.
