I tried convincing upstream before and never made it! And I actually
understand the authors of code like that and even copied that technique
sometimes, because it might be harder to write the interactive spec for
both interactive and programmatical use than to write the function
itself, and then there is no need for a wrapper command or interactive
(lambda ...) expression when it comes to define a key for that command.

But OTOH its a shame that many commands are hard/impossible to reuse in
programs because of this 'trick'.
