Is it standard practice to accept more specifics (append IPv4 "le /24" and IPv6 "le /48")?

There was an blog post written somewhere (unfortunately I cannot locate it) that urged caution as to how you configure more specifics at RIRs and doing it the wrong way opened you up to spoofing or somesuch. I seem to recall the obvious way (your suggested "append le/24" etc.) was very much not recommended. No doubt some kind soul on list will have that blog post in their bookmarks and/or others may wish to comment on the concept.
