----------------------------------------

The alternatives are taking us away from where we want to be – Tags integrated
into Cell – or they require a bunch of retrofit for which we do not have time.
Tag-use by CPs is rare in the scheme of things. An ugly typecast is ok for now
I'd say.

Currently the only concern from me is that encouraging cp user to use
{{ExtendedCell}} may hurt the philosophy we try to tell cp user - DONT touch
the -red button- internal methods which may corrupt your data.
Perhaps it is time to introduce the {{RawCell}}. All new tag-related methods be
added to {{RawCell}}. If we are ready to put the tags methods in Cell, we can
just remove them from {{RawCell}} as it is a subclass of {{Cell}} - no
competability will be broken
> Make Tag IA.LimitedPrivate and expose for CPs

> We need to make tags as LimitedPrivate as some use cases are trying to use
> tags like timeline server. The same topic was discussed in dev@ and also in
> HBASE-18995.
> Shall we target this for beta1 - cc [~saint....@gmail.com].
> So once we do this all related Util methods and APIs should also move to
> LimitedPrivate Util classes.
