Actually dark matter is only known through it's gravity interactions"... Sagittarius A* ... basically serves as a gravitational anchor for the entire Milky Way."
Per the hypothized 'dark matter' that would be the question,
is the tremendous mass of DM the mass/gravity anchor OR is it the central black hole?
I think Sgr A* is, partly because no one has ever even proposed what physics forces and events whip the DM cream into shapes that relatively neatly center around Sgr A*.
Made up invisible matter needs made up invisible physics to move it around,
that has no effect on real, visible matter.
And keep in mind DM doesn't respond to gravity, including its own, anywhere in a galaxy.
