Even extremely hot lasers, you have to keep trained on a single spot to have them burn through anything. The idea that you could reliably do this on a spinning, flying rocket in realtime seems pretty incredible.
Laser beams are also generally easily defeated by fog or smoke or clouds, which is already abundant in any warzone but which could surely be easily added as a countermeasure.
If these things work at all, there are likely many caveats.
To add to this, the alternative to trying to slow burn through a rocket like you mentioned is to use pulse lasers, but not only do they still suffer from blooming, they're also a massive power drain by comparison and unlikely to be viable for long because of that
