But the roots will keep growing ...

No they won't, not if you keep the tree trimmed. They have no need to.

Not so. Even trees that have been regularly pollarded will grow massive
root structures over the years. The trunk increases in girth every year,
and so do the roots supporting it.

We were talking of coppicing not polling. Root growth expands to match
needs above ground.
