I.e. The whole concept of pluggable functions is legacy. If
reverse-compatibility wasn't an issue they'd all be removed.

I just added a sentence to the "Pluggable
Codex article for the next person wondering about the seemingly random
choice of functions that are pluggable:

"Pluggable functions are no longer being added to WordPress core. All new
functions instead use filters on their output to allow for similar
overriding of their functionality."
