Yes, but when and how? Some things like the dormant season; others hate
it.

Yes, quite. I offered it only for the harsh.

However, the RHS Pruning guide is a bit more helpful:

"Train as a central-leader standard, pruning when dormant, but do not
remove laterals until they begin to die back as a result of shading.
Never tip-prune to encourage dense growth".

It also says "Always choose a lanky, open young tree" which implies that
lanky is good
