Depends how far back you go with "traditional". Originally Acol opened the suit below the singleton, so 1S. This changed about 40 years ago to become the middle suit with a black singleton - ie 1H with 4441.
You are being very generous here Gordon. My memory is that the "new" method was in the blue book, which was published around 1970 (71 I think).

The worst option is to open 1D and rebid 2D. Those who choose this option have not thought through the ramifications. You do not have a balanced hand - no 1NT opening or rebid, you do not raise C, s what do you have? Either a 4 card M with a hand not good enough to reverse, or 6D. Regardless, partner will overvalue the DK.
Or perhaps they have thought them through better than you have. Having the sequence 1♦ - 2♣; 2♦ forcing for a round can be extremely useful on some hands. It does have knock-on effects to the minimum strength requirement for the 2♣ response along with some other subtleties. There are other solutions possible for this too of course - no doubt you think have looked into every option in more detail than any of the very strong players and theorists who advance such methods...

My copy of Precision Bidding in Acol recommends that with 4441 (any singleton) with one poor suit you treat it as a two suiter. I can find no book on Acol that recommends opening 1D with 4441, singleton club. A wide range 2NT rebid would be 15+ (assuming 12-14 NT) so is not an option.
It started to come in in the 80s along with some other ideas taken from America such as opening 1♠ with 5-5 in the black suits. The first Acol book I saw it in was a Master Bridge series entry from Ron Klinger. It was actually the early 90s by the time I read it but the publication date of the book was late 80s.

err no real acol player opens this 1♥ ever. Yes if it was QJx, AKQJ, xxxxx, x you might choose to missort your hand, but not for that heart suit.
They did in the 60s. Some of the 70s Acol books explicitly mentioned the practice and pointed out that it was to be avoided. The simple truth is that it is a good way of playing in a 4-2 heart fit when a 5-3 diamond fit is available. I think only a rank beginner would do this these days.
