Have there been talks about the best practices to accept things smaller than a

Hi Justin,
The short version is: it could happen but it won't. There's no
technical obstacle. It's purely administrative. Tens of thousands of
organizations would have to agree to accept smaller prefixes.That
would only happen if there was something in it for them to start doing
so, something major. And even then it would be a hard lift. There
isn't. Some of those organizations run BGP set up by the last guy, the
current gut doesn't really grok it, and he certainly doesn't subscribe
to any information channels where it's discussed. So it's not going to
happen.
The "other problem" is, every day more gear receiving full routes gets
closer to (or farther past) the point where the resources to hold either
the FIB or RIB just aren't there. For those using these devices, lowering
the bar and bringing in another 100k or so routes in short order just
isn't an option. /24 has been the de facto threshold for routes in the v4
table long enough that I wouldn't want to be dependent on that changing.
