Why so orthodox?
Many Bluetooth-controlled devices are indeed just gimmicks, and having bespoke apps with proprietary interfaces is a nuisance and bad form (Bluetooth or otherwise).
There is no excuse not to openly document this stuff. These products are basically eWaste waiting to happen; no way all apps will be available and work as long as the devices.
For example; one of my test printers for SeaPrint has an app to set WiFi configuration - it is already broken and can’t connect to APs and since it is proprietary there is nothing to be done about it whatsoever.
We most definitely should be voting with our feet and wallets against this BS.
Using Sailfish only as a means of running Android apps kind of defeats the purpose.
However(!), the Android App Support enables enables regular people to live regular lives as part of modern society.
If it can grow Bluetooth, NFC and WiFi control support - great! If it can’t, or comes at basically the cost of half an OS and is not feasible, so be it.
Where this midpoint lies will be different for everyone.
Just consider that none at all will be too hard for most, and all is the same as giving up.
For example; i am emailing politicians left right and center about the abysmal state of eID here in Sweden. They actually seem to mostly agree, but everything is super slow. In the meantime, i’m quite happy that the current crap works on SFOS.
