My opinion that unless people demonstrate that they need this, e.g. in a
product, etc, we should not merge this stuff.

We recently merged fastmap, which is a big chunk of code, and it looks
like no one really needs it. There was a problem report, and Richard
promised to look, but did not. I do not blame him, he is a busy guy. But
this shoes that this feature is not really needed, while adds
maintenance burden.

To put it differently, I do recommend to merge more UBI-related code
without a solid user-base.
