Yes.
Unfortunately the CAA muddied the waters somewhat by trying to be clever and proposing some ridiculous phraseology in an attempt to make things more clear.
So now, when we say 'climb now' we often get quizzed by pilots if 'now' means 'now'!!
You will hear various iterations...
'Climb now...'
'Climb unrestricted...'
'Climb now unrestricted...'
Unfortunately since the CAA intervened, pilots are more confused.
