(With release manager hat on)

Actually I would think it is OK. In terms of X feature count at this
point of time (T) and on 4.5 feature freeze day (T-RC0) if the number of
features is greater or equal we are OK.

What is bad if the amount of features on T-RC0 is less than now (so say
X-1 features). That is not the case.
