I hope the developers are aware of such issues.
Of course we are. Both I, K1773R and BroTroxer have had discussion on this. Implementations of zerocoin, coloredcoin etc have been discussed. And you will probably see one of the features in Anoncoin in the future, and if none of them, another system that's similar and does the same job. No schedule is set on this. However, the latency problem is known, but not addressed yet. Note, none of those features will come in the next release, but probably the next after this.
