Well, we can definitively state that the NOT makes this unindexable.
You need a WHERE clause that looks like
indexed-column indexable-operator pseudo-constant
which this isn't, nor does << have a negator

On an RDMS which I used in the 1990s and 2000s, b-tree indices of sequences
would get unbalanced, since every new leaf was added to the far right

Sure, they would auto-balance *to a degree* during node splits, but all
