If we remove SBD at the same time, the overall complexity doesn't get higher.

For me SBD is a fundamental part of the ecosystem. But I get your point: SBD is quite useless without the peg.

But Steemit.com hasn't yet implemented it in the UI, you have to use cli_wallet instead.

That's really a shame. In HF20 they aim for a mobile app, yet still the basic functionality is missing on the webpage. A classic example of messing up the priorities.
