I would think that, at least in the case of _Microraptor gui_, the fact that
long feathers appeared on the legs all the way down to the distal metatarsus
argues strongly in favor of arboreal habits for _Microraptor_. Had _M. gui_
been terrestrial, I'd imagine the distal-most feathers would have been destroyed
in the process of walking on the ground

Aside from this, absence of a reverted hallux in other theropods does not preclude their being able to climb or be in a tree ... it only prohibits "effective" perching and grasping on branches two-leggedly.
This doesn't mean no other bird or other maniraptoran theropod (or even any small
coelurosaur) could climb or get into a tree for at least PART of it's habitus.
