Agree with mentioned issue. If we want to give value to users from proposed
change i think we need to do some tweaking. Last time i installed all Noto
CJK fonts and size was around 1GB+.   As a non-CJK user, i definitely not
required entire collection of CJK fonts but only 1 variant is sufficient to
avoid Tofu.

Will be nice if we can allow this exception to sub-packaging at variant
level for this release and try other options for FY19 (.ttc)
