1. I'd love to see Recaller not so buggy. It worked for me untill some change in CSSU, IIRC. I love it for no need to be opened for recording phone calls like say Orcchiette. Also it is much faster to press a button on the desktop, rather to open an app and press button there.

2. I desperately need a working MessageBlocker app. I'm so tires of SMS spam. Since v0.3 this app doesn't block anything.

3. You say we don't need another watsapp client, but I don't see a working libpurple version. I think having all messaging protocols in one place is a good idea. It could be just a messaging client without file or photo interchanging or anything else telepathy doesn't support. The same is for new google hangouts.
