Actually, when apt installs something new, it considers Recommends:
for *all* packages it installs. So if A depends on B, and B
recommends C, and you install A, C will be installed too (unless you
disable installing recommends). Ditto for the case when A
*recommends* B, etc.
In short, by default apt installs Recommends for everything it
installs.
What you've written here does not match the situation I described.
What if, before asking to install A, B had already been installed,
but without C?
If you earlier install B without installing its recommendations, - sure,
apt wont install these recommendations when you later install something
else which depends on (or recommends) B.
The whole Recommends thing, and skipping installing recommendations,
assumes that the user knows what he's doing, and can deal with the
possible consequences. In this particular case, just by reading the
error message, I would immediately see which mechs are available to
begin with - like, asking google how to list installed sasl auth
mechanisms. Or something like this.
