Nature is hard to kill.
Until it isn’t.
I have a Mulberry tree in my yard that is doing this. I cut it down 2 years ago because most of it was leaning over my neighbors yard. Tallest branches are around 10’ or a little over 3m.
You coppiced the tree.
You could also pollard a tree, which is just cutting it at a higher level.
I’m guessing from those epicormic shoots you would then train a leader? I don’t think pines get epicormic shoots either when they die back or are cut to the base they don’t send up those shoots.
You’d still want a balanced tree though.
Best to let nature take its course.
I’m not sure what will happen in this example where the main trunk was cut down to a stump.
Maybe our descendants decades from now will see a squat branchy hedge like thing emanating from the stump, or maybe some shoots will curl back and grow out over the stump top, resulting in something that appears more tree-like.
It’ll look like these if left alone: https://www.alamy.com/stock-photo/coppiced-tree-winter-woodland.html?pseudoid=C06657A9-750C-4B78-A69A-8E981609AE0E&sortBy=relevant
They don’t. Conifers just die when cut back.
