Is it acceptable to just remove properties ?

What else you suggest I should do? also add document here to explain
why remove them?

I would suggest to either wait for Rob's feedback or check how other bindings
handle deprecated properties.

Rob already reviewed this patch and gave his reviewed-by[1], you can see it in 
the
patch tags.

Ah, ok. Guess you are ok then. Sorry, should have noticed.
