Smaller than a /24 for BGP?

How do you plan on getting rid of all the filters that don’t accept anything less than a /24?

In all seriousness If I have these, I’d imagine everyone else does too.

Have there been talks about the best practices to accept things smaller than a /24? I qm seeing more and more scenarios where folks need to participate in BGP but they do not need a full /24 of space.  Seems wasteful.  I know this would bloat the routing table immensely.  I know of several folks who could split their /24 into /25s across a few regions and still have plenty of IP space.
