Yes, that is perfectly fine for me.

Sorry, I don't understand what it is you would like me to do.
I do not have access to a KDE development setup, so I cannot push any new commits.

Here are two screenshots showing the difference of the second change.

That's almost good, but the flag name should be more general, think like for example you would remove the manage bool and convert it to a flag too, so that if it the future someone needs to add a new flag, they can add it to that enum and don't need a new parameter.

Am I making sense?

Sorry for the duplicate updates, I messed up my Arcanist commands.

Restore binary compatibility and introduce alignment flags

I have to admit, I don't know how to implement a version with flags correctly.

You are right, of course. Magic constants are bad.
