Minimum prefix length?

Title: Minimum prefix length?

A few years ago I had an issue with a few of the larger carriers rejecting my routes (from a natural Class B space) because their prefix length was too short (at one point I simply had the /16 divided into two /17's and this still got rejected in some places).  I can't remember which carriers exactly, but it may have been some larger transit providers like AboveNet/etc.

Anyone know what the current attitude is by carriers about this?  Nowadays with ever-growing memory and CPU it doesn't seem like it's as much of an issue.  In an environment where we're all trying to conserve address space watching natural boundries doesn't seem all that smart.
