A lot of terminals support CSI Ps S. Currently we only allow them to use scrollback-up if they advertise it via XTGETTCAP. This seems surprising; it's better to make visible in fish script whether this is supposed to be working. The canonical place is in "bind ctrl-l" output. The downside here is that we need to expose something that's rarely useful. But the namespace pollution is not so bad, and this gives users a nice paper trail instead of having to look in the source code.
