Perhaps, the changes for UIF (user interaction flag) is not needed to be backported now.
Because the feature is not yet used by any OpenPGP card implementation.
I am testing with Gnuk, but it's still experimental even for Gnuk.

I decided not to backport UIF things.
Other fixes (KDF and memory leak) were done.
If this decision will be re-evaluated, remember the backport of the commit rG05d163aebc04: scd: Make "learn" report about KDF data object. doesn't have UIF change.

I have OpenPGP Smart Cards V3.3 from FLOSS Shop - these should support UIF, shouldn't they? I assumed so, because the spec includes it as of 3.0.

I was wondering how to enable it in gpg --card-edit (GPG version 2.2.12-1ubuntu3), but if I understand it correctly, it's currently not supported in GPG 2.2.x?

For OpenPGP card v3.x, the data object is available, but it doesn't come with a button physically. So, I think it's no use.

Oh. I have to admit, I kinda just expected it to use the green OK button on the smart card reader ^^
