If that is the case ...

... it is a bit premature to lose this TODO comment (which was
written, inspired by what I wrote ages ago, in [*1*]), until that
happens.

On the other hand, you can and should lose our own #define
UNINTERSTING here even with this "slab stores a single u64 word"
rewrite, and instead use the common one from <revision.h> header
file.

Thanks.
