That '2000 peer ASN's' value is likely very, very inflated. I have prefixes that would look like I am peering with 3549 directly in many places that I do not.
L3 has for some time had a partial as-merge community that you can set so that if you announce a prefix to 3356, they'll mirror it over to 3549 in the same location and strip 3356 from the as-path. The reverse also works for an announcement to 3549 mirrored over to 3356. They're doing some inter-as option c juju to make all that work. Doesn't change the point that 3549 is still around 8 years later and likely will be for 8 more, but yeah. :) I'm sure efforts to make that happen have a plethora of roadblocks such that it would cost 10x more to get rid of it than it would to just leave it as is and just shrink it when possible.
