I mean, that providers have always either refused to accept small address
blocks (/24 has been the "limit" for many years, before that it was RIR
allocation boundaries or classful addressing). Those that reluctantly
accept blocks smaller than /24 usually caveat that it won't actually work
on the global Internet. This seems to have held back routing of small
blocks despite there always been a subset of demand, typically from
corporates for routing small blocks.

And I'd say that I do know it - there are no /25-32 addresses routable
across a majority of the global internet.
