I didn’t mean to offend you, sorry if I did.
None taken. 
It’s just that I generally don’t ‘downvote’ (in quotes, since it wasn’t really a proper feature request) stuff that I don’t use or care about, unless they will interfere with my workflow. So when I see people being negative about other peoples’ requests I just don’t get it. Sorry if I was offensive too, I just get frustrated when this happens.
Many users have routerboards behind DSL modems as bridges and use PPPoE client to connect to the internet.
And many more new users start to adopt this setup since the modems/routers the ISPs give are really bad most of the time and routerboards are just awesome!
I have personally set up numerous routerboards with the above configuration and it works flawlessly!
So I believe Mikrotik is indirectly already in that market, it just needs a modem to attach onto a routerboard to sell it as one complete device instead of having to use the ISP’s modem (which nowadays even comes with a completely locked firmware and cannot change it to bridge mode ugggh 
).
I am sure that many users will go for it! I know I would!
Less devices in the office/home, less cables, less power consumption and a single plane of management (aka Winbox awesomeness!).
Generally it’s for the best
