Replying to [comment:3 tscrim]:
> Do you think it is worthwhile overriding this method in those classes as
an optimization?
No. I think that #18776 is what could and should be done as an
optimization. Changing for example `is_bounded()` to a function just
returning `True` in lattices is of little value. It is different thing if
there is faster way to compute, say, `dimension()`, on lattices than on
general posets.
