Can playcanvas please add bones and rigging to the engine?
Skinned animation playback is supported by the engine (for a long time):

Maybe you mean support for rigging characters in editor?
yes
That’s not support right now in the PlayCanvas editor, it’s definitely a complex pipeline more suited to traditional modelling software.
You are free though to add a feature request about it:
