Why DO....VARYING is obsolete?

Subject contains the question, I‘m interested in the technical reason for marking the command as obsolete.

I guess you know the documentation.

Do you think that kind of programming, that depends on internal memory layout, is still appropriate nowadays?

Just mentioning alignment gaps ...

I hoped, YOU will read this question, Horst 😉

Of course, I know it‘s documentation and I never used this command (in fact, I never understood it *lol*), but in another (german) forum this question has been posted and I didn‘t know the answer.

What do you mean with „alignment gaps“?

I had an issue with alignment gaps years ago. In order to test for equality quickly, I converted my key values to a hex string. It didn't work, because of the undefined values in the alignment gap.

Thank you very much! Developers might be potientally interested in facts like this, so the docu should give these informations.
