Do Origins Heroes still upload to the Keep?

Yes.

I think they will soon disable that function as it is not in their interest to keep active the managament of old and uneccessary data,one day they will do as davesin said and just allow to make characters comepltely from the keep,with players having to just add the protrait.strange they didn't it yet after like 9 years from the game.

I have two of my favorite wardens uploaded on the Keep.  My Female Amell and my Female Cousland, all decked out in their respectable OP armour (but than again, I did did do that nearly two years ago.... so...)

Thanks for the replies people.
I did finally manage to get a character uploaded yesterday.
Not the one I'm currently playing, just one I created to test a theory.
The trouble with the default Heroes, is it won't let you change their class, so I couldn't make my Dalish Mage.
However I do have a Dalish Mage uploaded from when it was working semi regularly.
The amount of times I got this error message yesterday while trying to access my heroes, makes me wonder if they haven't reduced the available bandwidth for Origin character uploads?

No, it's quite capable of uploading a modded Dalish Mage.

But this is the thing, the old player profile page upload was designed for Origins, a game that officially supported and encouraged modding.
So you could upload the player you actually played.
If they had modded armor or had learned modded spells, you could see them.
Dragonage Keep was not meant as a replacement for the old Origins system, just a way to get your sex class and surname into Inquisition, a game that doesn't officially support modding and makes no allowances for it.
I don't play Inquisition, so I don't actually need the Keep, but I clicked on an old bookmark by mistake and noticed that none of my wardens of the last few months had been uploaded and wondered if they had stopped that feature all together.
