I look forward to hearing what more informed people know about how push notifications will work, but I have a couple thoughts to contribute to this discussion:
- I’d take the privacy/security trade-off of per-app connections (versus single tunnel to a vendor) any day.
- The cost of data has lowered while bandwidth has increased year over year since forever, so I’m of the opinion that a little overhead for the price of better separation/security is worth it.
- I wonder if the FOSS dev community will face a paradigm dilemma in the near future, whereby app design is influenced by battery saving than anything else, for the reasons you specified. Maybe batching will become more popular?
You bring up an interesting point.
